2025-12-17perf vendor power9 nest metrics: Correct unit from MB to MiBIan Rogers
6.1e-5 is very close to 1/16384, where 16384 is 2^14, i.e. a power of 2. When units are in powers of 2 the IEC unit is MiB (mebibytes) rather than MB (megabytes) where the values are powers of 10. This patch corrects the unit for uniformity and because such units may be pattern matched against.

Newer glibc versions return const char for strchr() when the 's' arg is const, change the return variable to const to match that.

2025-12-17spi: add driver for NXP XSPI controllerHaibo Chen
Add driver support for NXP XSPI controller. XSPI is a flexible SPI host controller which supports up to 2 external devices (2 CS). It support Single/Dual/Quad/Octal mode data transfer. The difference between XSPI and Flexspi: 1.the register layout is total different. 2.XSPI support multiple independent execution environments (EENVs) for HW virtualization with some limitations. Each EENV has its own interrupt and its own set of programming registers that exists in a specific offset range in the XSPI memory map. The main environment (EENV0) address space contains all of the registers for controlling EENV0 plus all of the general XSPI control and programming registers. The register mnemonics for the user environments (EENV1 to EENV4) have "_SUB_n" appended to the mnemonic for the corresponding main-environment register. Current driver based on EENV0, which means system already give EENV0 right to linux. This driver use SPI memory interface of the SPI framework to issue flash memory operations. Tested this driver with UBIFS and mtd_debug on NXP i.MX943 EVK board which has one spi nor MT35XU512ABA flash. Now this driver has the following key features: - Support up to OCT DDR mode - Support AHB read - Support IP read and IP write - Support two CS Reviewed-by: Frank Li <Frank.Li@nxp.com> Signed-off-by: Haibo Chen <haibo.chen@nxp.com> Link: https://patch.msgid.link/20251216-xspi-v7-2-282525220979@nxp.com Signed-off-by: Mark Brown <broonie@kernel.org>

2025-12-17ASoC: cs-amp-lib: Replace __free(kfree) with normal kfree() cleanupRichard Fitzgerald
Replace the use of __free(kfree) in _cs_amp_set_efi_calibration_data() with normal kfree() at the end of the function. Krzysztof Kozlowski pointed out that __free() can be dangerous. It can introduce new cleanup bugs. These are more subtle and difficult to spot than a missing goto in traditional cleanup, because they are triggered by writing regular idiomatic C code instead of using C++ conventions. As it's regular C style it's more likely to be missed because the code is as would be expected for C. The traditional goto also more obviously flags to anyone changing the code in the future that they must be careful about the cleanup. Arguably the traditional approach is more readable, and it avoids the manipulation of __free() pointers when the buffer is reallocated for resizing.

This driver is migrated to use threaded IRQ since commit 5972eb05ca32 ("spi: spi-mt65xx: Use threaded interrupt for non-SPIMEM transfer"), and we almost always want to disable the interrupt line to avoid excess interrupts while the threaded handler is processing SPI transfer.

2025-12-17can: j1939: make j1939_sk_bind() fail if device is no longer registeredTetsuo Handa
There is a theoretical race window in j1939_sk_netdev_event_unregister() where two j1939_sk_bind() calls jump in between read_unlock_bh() and lock_sock(). The assumption jsk->priv == priv can fail if the first j1939_sk_bind() call once made jsk->priv == NULL due to failed j1939_local_ecu_get() call and the second j1939_sk_bind() call again made jsk->priv != NULL due to successful j1939_local_ecu_get() call. Since the socket lock is held by both j1939_sk_netdev_event_unregister() and j1939_sk_bind(), checking ndev->reg_state with the socket lock held can reliably make the second j1939_sk_bind() call fail (and close this race window).

'struct configfs_item_operations' and 'configfs_group_operations' are not modified in these drivers. Constifying these structures moves some data to a read-only section, so increases overall security, especially when the structure holds some function pointers.

2025-12-17xfs: fix the zoned RT growfs check for zone alignmentChristoph Hellwig
The grofs code for zoned RT subvolums already tries to check for zone alignment, but gets it wrong by using the old instead of the new mount structure.

2025-12-17xfs: validate that zoned RT devices are zone alignedChristoph Hellwig
Garbage collection assumes all zones contain the full amount of blocks. Mkfs already ensures this happens, but make the kernel check it as well to avoid getting into trouble due to fuzzers or mkfs bugs.

2025-12-17gpiolib: of: Only compile in MT2701 quirk when it is needed.Daniel Palmer
The compiler cannot workout if this is actually needed or not so machines that will never need this code also get it. For example: m68k-linux-gnu-nm vmlinux | grep mt27 00135742 t of_find_mt2701_gpio Add some ugly ifdef'ery to get rid of it.

2025-12-17ALSA: usb-audio: Relax __free() variable declarationsTakashi Iwai
We used to have a variable declaration with __free() initialized with NULL. This was to keep the old coding style rule, but recently it's relaxed and rather recommends to follow the new rule to declare in place of use for __free() -- which avoids potential deadlocks or UAFs with nested cleanups. Although the current code has no bug, per se, let's follow the new standard and move the declaration to the place of assignment (or directly assign the allocated result) instead of NULL initializations. Note that there are still a few remaining __free(kfree) with NULL initializations; they are because of the code complexity (the data size calculation). Fixes: 43d4940c944c ("ALSA: usb: scarlett2: Clean ups with guard() and __free()") Fixes: 46757a3e7d50 ("ALSA: FCP: Add Focusrite Control Protocol driver") Fixes: f7d306b47a24 ("ALSA: usb-audio: Fix a DMA to stack memory bug") Signed-off-by: Takashi Iwai <tiwai@suse.de> Link: https://patch.msgid.link/20251216140634.171890-12-tiwai@suse.de
