2025-10-22comedi: fix divide-by-zero in comedi_buf_munge()Deepanshu Kartikey
The comedi_buf_munge() function performs a modulo operation `async->munge_chan %= async->cmd.chanlist_len` without first checking if chanlist_len is zero. If a user program submits a command with chanlist_len set to zero, this causes a divide-by-zero error when the device processes data in the interrupt handler path. Add a check for zero chanlist_len at the beginning of the function, similar to the existing checks for !map and CMDF_RAWDATA flag. When chanlist_len is zero, update munge_count and return early, indicating the data was handled without munging. This prevents potential kernel panics from malformed user commands.

2025-10-22mei: late_bind: Fix -Wincompatible-function-pointer-types-strictNathan Chancellor
When building with -Wincompatible-function-pointer-types-strict, a warning designed to catch kernel control flow integrity (kCFI) issues at build time, there is an instance in the new mei late binding code originating from the type parameter of mei_lb_push_payload(): drivers/misc/mei/mei_lb.c:211:18: error: incompatible function pointer types initializing 'int (*)(struct device *, u32, u32, const void *, size_t)' (aka 'int (*)(struct device *, unsigned int, unsigned int, const void *, unsigned long)') with an expression of type 'int (struct device *, enum intel_lb_type, u32, const void *, size_t)' (aka 'int (struct device *, enum intel_lb_type, unsigned int, const void *, unsigned long)') [-Werror,-Wincompatible-function-pointer-types-strict] 211 | .push_payload = mei_lb_push_payload, | ^~~~~~~~~~~~~~~~~~~ While 'unsigned int' and 'enum intel_lb_type' are ABI compatible, hence no regular warning from -Wincompatible-function-pointer-types, the mismatch will trigger a kCFI violation when mei_lb_push_payload() is called indirectly. Update the type parameter of mei_lb_push_payload() to be 'u32' to match the prototype in 'struct intel_lb_component_ops', clearing up the warning and kCFI violation.

2025-10-22misc: fastrpc: Fix dma_buf object leak in fastrpc_map_lookupJunhao Xie
In fastrpc_map_lookup, dma_buf_get is called to obtain a reference to the dma_buf for comparison purposes. However, this reference is never released when the function returns, leading to a dma_buf memory leak. Fix this by adding dma_buf_put before returning from the function, ensuring that the temporarily acquired reference is properly released regardless of whether a matching map is found.

2025-10-22apm-emulation: remove unused __apm_get_power_statusAhelenia Ziemiańska
The API for apm_get_power_status is "call it if it isn't NULL", except it's also initialised with a no-op __apm_get_power_status. This was added alongside apm_get_power_status in 2007. The apm_get_power_status symbol is used in these files: arch/arm/mach-pxa/sharpsl_pm.c:extern void (*apm_get_power_status)(struct apm_power_info *); arch/arm/mach-pxa/sharpsl_pm.c: apm_get_power_status = sharpsl_apm_get_power_status; arch/sh/boards/mach-hp6xx/hp6xx_apm.c: apm_get_power_status = hp6x0_apm_get_power_status; drivers/char/apm-emulation.c:void (*apm_get_power_status)(struct apm_power_info *) = __apm_get_power_status; drivers/char/apm-emulation.c:EXPORT_SYMBOL(apm_get_power_status); drivers/char/apm-emulation.c: if (apm_get_power_status) drivers/char/apm-emulation.c: apm_get_power_status(&info); drivers/macintosh/apm_emu.c: apm_get_power_status = pmu_apm_get_power_status; drivers/macintosh/apm_emu.c: if (apm_get_power_status == pmu_apm_get_power_status) drivers/macintosh/apm_emu.c: apm_get_power_status = NULL; drivers/power/supply/apm_power.c: apm_get_power_status = apm_battery_apm_get_power_status; drivers/power/supply/apm_power.c: apm_get_power_status = NULL; include/linux/apm-emulation.h:extern void (*apm_get_power_status)(struct apm_power_info *); All of them are compatible with the API (post-remove UAFs notwithstanding) and don't even read it except to compare with their own values; on a cursory glance this doesn't seem to have ever not been the case.

2025-10-22rust: replace `CStr` with `core::ffi::CStr`Tamir Duberstein
`kernel::ffi::CStr` was introduced in commit d126d2380131 ("rust: str: add `CStr` type") in November 2022 as an upstreaming of earlier work that was done in May 2021[0]. That earlier work, having predated the inclusion of `CStr` in `core`, largely duplicated the implementation of `std::ffi::CStr`. `std::ffi::CStr` was moved to `core::ffi::CStr` in Rust 1.64 in September 2022. Hence replace `kernel::str::CStr` with `core::ffi::CStr` to reduce our custom code footprint, and retain needed custom functionality through an extension trait. Add `CStr` to `ffi` and the kernel prelude.

The file had an old cleanup_module still in use which could be updated with __exit module function although its init_module is indeed newer however the cleanup_module was still using the older version of exit.

2025-10-21Merge patch series "Remove UFS_DEVICE_QUIRK_DELAY_AFTER_LPM quirk"Martin K. Petersen
Bao D. Nguyen <quic_nguyenb@quicinc.com> says: Multiple ufs device manufacturers request support for the UFS_DEVICE_QUIRK_DELAY_AFTER_LPM quirk in the Qualcomm's platform driver. After checking further with the major UFS manufacturers engineering teams such as Samsung, Kioxia, SK Hynix and Micron, all the manufacturers require this quirk. Since the quirk is needed by all the ufs device manufacturers, remove the quirk in the ufs core driver and implement a universal delay for all the ufs devices. In addition to verifying with the public device's datasheets, the ufs device manufacturer's engineering teams confirmed the required vcc power-off time for the devices is a minimum of 1ms before vcc can be powered on again. The existing 5ms delay implemented in the ufs core driver seems too conservative, so replace the hard coded 5ms delay with a variable default to 2ms setting to improve the system resume latency. The platform drivers can override this setting as needed. Link: https://patch.msgid.link/cover.1760383740.git.quic_nguyenb@quicinc.com Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
