2026-04-12i3c: mipi-i3c-hci: Add quirk to allow IBI while runtime suspendedAdrian Hunter
Some I3C controllers can be automatically runtime-resumed in order to handle in-band interrupts (IBIs), meaning that runtime suspend does not need to be blocked when IBIs are enabled. For example, a PCI-attached controller in a low-power state may generate a Power Management Event (PME) when the SDA line is pulled low to signal the START condition of an IBI. The PCI subsystem will then runtime-resume the device, allowing the IBI to be received without requiring the controller to remain active. Introduce a new quirk, HCI_QUIRK_RPM_IBI_ALLOWED, so that drivers can opt-in to this capability via driver data.

2026-04-12crypto: qat - fix IRQ cleanup on 6xxx probe failureGiovanni Cabiddu
When adf_dev_up() partially completes and then fails, the IRQ handlers registered during adf_isr_resource_alloc() are not detached before the MSI-X vectors are released. Since the device is enabled with pcim_enable_device(), calling pci_alloc_irq_vectors() internally registers pcim_msi_release() as a devres action. On probe failure, devres runs pcim_msi_release() which calls pci_free_irq_vectors(), tearing down the MSI-X vectors while IRQ handlers (for example 'qat0-bundle0') are still attached. This causes remove_proc_entry() warnings: [ 22.163964] remove_proc_entry: removing non-empty directory 'irq/143', leaking at least 'qat0-bundle0' Moving the devm_add_action_or_reset() before adf_dev_up() does not solve the problem since devres runs in LIFO order and pcim_msi_release(), registered later inside adf_dev_up(), would still fire before adf_device_down(). Fix by calling adf_dev_down() explicitly when adf_dev_up() fails, to properly free IRQ handlers before devres releases the MSI-X vectors.

2026-04-12crypto: talitos - fix SEC1 32k ahash request limitationPaul Louvel
Since commit c662b043cdca ("crypto: af_alg/hash: Support MSG_SPLICE_PAGES"), the crypto core may pass large scatterlists spanning multiple pages to drivers supporting ahash operations. As a result, a driver can now receive large ahash requests. The SEC1 engine has a limitation where a single descriptor cannot process more than 32k of data. The current implementation attempts to handle the entire request within a single descriptor, which leads to failures raised by the driver: "length exceeds h/w max limit" Address this limitation by splitting large ahash requests into multiple descriptors, each respecting the 32k hardware limit. This allows processing arbitrarily large requests.

2026-04-12crypto: jitterentropy - replace long-held spinlock with mutexHaixin Xu
jent_kcapi_random() serializes the shared jitterentropy state, but it currently holds a spinlock across the jent_read_entropy() call. That path performs expensive jitter collection and SHA3 conditioning, so parallel readers can trigger stalls as contending waiters spin for the same lock. To prevent non-preemptible lock hold, replace rng->jent_lock with a mutex so contended readers sleep instead of spinning on a shared lock held across expensive entropy generation.

2026-04-12drm/xe/pf: Perform fair scheduling auto-provisioningMichal Wajdeczko
Default VF scheduling configuration is the same as for the PF and includes unlimited execution quantum (EQ) and unlimited preemption timeout (PT). While this setup gives the most flexibility it does not protect the PF or VFs from other VF that could constantly submit workloads without any gaps that would let GuC do a VF-switch. To avoid that, do some trivial auto-provisioning and configure PF and all VFs with 16ms EQ and PT. This setup should allow GuC to perform a full round-robin with up to 63 VFs within 2s, which in turn should match expectations from most of the VMs using VFs.

2026-04-12ALSA: sscape: Add suspend and resume supportCássio Gabriel
The SoundScape ISA driver has lacked suspend and resume callbacks since commit 277e926c9b27 ("[ALSA] sscape - Use platform_device"). A plain snd_wss resume is not sufficient for SoundScape. Resume also needs to restore the board-specific gate-array routing, and non-VIVO boards need to reinitialize the probe-time MIDI firmware and MIDI control state when the MPU-401 side was enabled during probe. That firmware reload can be handled in-kernel because commit acd47100914b ("ALSA: sscape: convert to firmware loader framework") moved the driver to request_firmware(). Add ISA and ISA-PnP PM callbacks, reconfigure the board on resume, reload the non-VIVO MIDI firmware, restore the MIDI state, and then resume the WSS codec. If MIDI firmware reload fails, keep the WSS resume path alive and leave MIDI unavailable instead of failing the whole device resume.

2026-04-12ALSA: sscape: Cache per-card resources for board reinitializationCássio Gabriel
The SoundScape driver programs the gate-array directly from the global resource arrays during probe. That is sufficient for initial bring-up, but a PM resume path also needs the resolved per-card IRQ, DMA, MPU IRQ and joystick settings after probe has finished. Store the resolved resources in struct soundscape and move the board setup into a reusable helper. Also factor the MIDI state programming so the same sequence can be reused by a later PM resume path. This is preparatory work for suspend/resume support and is not intended to change runtime behaviour.

2026-04-12X.509: Fix out-of-bounds access when parsing extensionsLukas Wunner
Leo reports an out-of-bounds access when parsing a certificate with empty Basic Constraints or Key Usage extension because the first byte of the extension is read before checking its length. Fix it. The bug can be triggered by an unprivileged user by submitting a specially crafted certificate to the kernel through the keyrings(7) API. Leo has demonstrated this with a proof-of-concept program responsibly disclosed off-list.

2026-04-12crypto: af_alg - Fix page reassignment overflow in af_alg_pull_tsglHerbert Xu
When page reassignment was added to af_alg_pull_tsgl the original loop wasn't updated so it may try to reassign one more page than necessary. Add the check to the reassignment so that this does not happen. Also update the comment which still refers to the obsolete offset argument.

2026-04-11clk: visconti: pll: initialize clk_init_data to zeroBrian Masney
Sashiko reported the following: > The struct clk_init_data init is declared on the stack without being > fully zero-initialized. While fields like name, flags, parent_names, > num_parents, and ops are explicitly assigned, the parent_data and > parent_hws fields are left containing stack garbage. clk_core_populate_parent_map() currently prefers the parent names over the parent data and hws, so this isn't a problem at the moment. If that ordering ever changed in the future, then this could lead to some unexpected crashes. Let's just go ahead and make sure that the struct clk_init_data is initialized to zero as a good practice.

2026-04-11clk: fsl-sai: Add MCLK generation supportMarek Vasut
The driver currently supports generating BCLK. There are systems which require generation of MCLK instead. Register new MCLK clock and handle clock-cells = <1> to differentiate between BCLK and MCLK. In case of a legacy system with clock-cells = <0>, the driver behaves as before, i.e. always returns BCLK. Note that it is not possible re-use the current SAI audio driver to generate MCLK and correctly enable and disable the MCLK. If SAI (audio driver) is used to control the MCLK enablement, then MCLK clock is not always enabled, and it is not necessarily enabled when the codec may need the clock to be enabled. There is also no way for the codec node to specify phandle to clock provider in DT, because the SAI (audio driver) is not clock provider. If SAI (clock driver) is used to control the MCLK enablement, then MCLK clock is enabled when the codec needs the clock enabled, because the codec is the clock consumer and the SAI (clock driver) is the clock provider, and the codec driver can request the clock to be enabled when needed. There is also the usual phandle to clock provider in DT, because the SAI (clock driver) is clock provider.
