2025-02-05ACPI: property: Fix return value for nval == 0 in acpi_data_prop_read()Andy Shevchenko
While analysing code for software and OF node for the corner case when caller asks to read zero items in the supposed to be an array of values I found that ACPI behaves differently to what OF does, i.e. 1. It returns -EINVAL when caller asks to read zero items from integer array, while OF returns 0, if no other errors happened. 2. It returns -EINVAL when caller asks to read zero items from string array, while OF returns -ENODATA, if no other errors happened. Amend ACPI implementation to follow what OF does.

2025-02-05cpufreq: airoha: modify CONFIG_OF dependencyArnd Bergmann
Compile-testing without CONFIG_OF leads to a harmless build warning: drivers/cpufreq/airoha-cpufreq.c:109:34: error: 'airoha_cpufreq_match_list' defined but not used [-Werror=unused-const-variable=] 109 | static const struct of_device_id airoha_cpufreq_match_list[] __initconst = { | ^~~~~~~~~~~~~~~~~~~~~~~~~ It would be possible to mark the variable as __maybe_unused to shut up that warning, but a Kconfig dependency seems more appropriate as this still allows build testing in allmodconfig and randconfig builds on all architectures. An earlier commit, b865a8404642 ("cpufreq: airoha: Depends on OF"), tried to fix it incorrectly. ARCH_AIROHA already requires CONFIG_OF, so this change does nothing, and the dependency is still missing for the COMPILE_TEST case. Fix it properly.

2025-02-06kbuild: keep symbols for symbol_get() even with CONFIG_TRIM_UNUSED_KSYMSMasahiro Yamada
Linus observed that the symbol_request(utf8_data_table) call fails when CONFIG_UNICODE=y and CONFIG_TRIM_UNUSED_KSYMS=y. symbol_get() relies on the symbol data being present in the ksymtab for symbol lookups. However, EXPORT_SYMBOL_GPL(utf8_data_table) is dropped due to CONFIG_TRIM_UNUSED_KSYMS, as no module references it in this case. Probably, this has been broken since commit dbacb0ef670d ("kconfig option for TRIM_UNUSED_KSYMS"). This commit addresses the issue by leveraging modpost. Symbol names passed to symbol_get() are recorded in the special .no_trim_symbol section, which is then parsed by modpost to forcibly keep such symbols. The .no_trim_symbol section is discarded by the linker scripts, so there is no impact on the size of the final vmlinux or modules. This commit cannot resolve the issue for direct calls to __symbol_get() because the symbol name is not known at compile-time. Although symbol_get() may eventually be deprecated, this workaround should be good enough meanwhile.

2025-02-06scripts/Makefile.extrawarn: Do not show clang's non-kprintf warnings at W=1Nathan Chancellor
Clang's -Wformat-overflow and -Wformat-truncation have chosen to check '%p' unlike GCC but it does not know about the kernel's pointer extensions in lib/vsprintf.c, so the developers split that part of the warning out for the kernel to disable because there will always be false positives. Commit 908dd508276d ("kbuild: enable -Wformat-truncation on clang") did disabled these warnings but only in a block that would be called when W=1 was not passed, so they would appear with W=1. Move the disabling of the non-kprintf warnings to a block that always runs so that they are never seen, regardless of warning level.

Current rsnd driver supports Synchronous SRC Mode, but HW allow to update rate only within 1% from current rate. Adjust to it. Becially, this feature is used to fine-tune subtle difference that occur during sampling rate conversion in SRC. So, it should be called within 1% margin of rate difference. If there was difference over 1%, it will apply with 1% increments by using loop without indicating error message.

rsnd_kctrl_accept_runtime() (1) is used for runtime convert rate (= Synchronous SRC Mode). Now, rsnd driver has 2 kctrls for it (A): "SRC Out Rate Switch" (B): "SRC Out Rate" // it calls (1) (A): can be called anytime (B): can be called only runtime, and will indicate warning if it was used at non-runtime.

Commit 0d73a55208e9 ("ima: re-introduce own integrity cache lock") mistakenly reverted the performance improvement introduced in commit 42a4c603198f0 ("ima: fix ima_inode_post_setattr"). The unused bit mask was subsequently removed by commit 11c60f23ed13 ("integrity: Remove unused macro IMA_ACTION_RULE_FLAGS"). Restore the performance improvement by introducing the new mask IMA_NONACTION_RULE_FLAGS, equal to IMA_NONACTION_FLAGS without IMA_NEW_FILE, which is not a rule-specific flag. Finally, reset IMA_NONACTION_RULE_FLAGS instead of IMA_NONACTION_FLAGS in process_measurement(), if the IMA_CHANGE_ATTR atomic flag is set (after file metadata modification). With this patch, new files for which metadata were modified while they are still open, can be reopened before the last file close (when security.ima is written), since the IMA_NEW_FILE flag is not cleared anymore. Otherwise, appraisal fails because security.ima is missing (files with IMA_NEW_FILE set are an exception).

Currently, there are several files in drm/amd/display that aim to have a higher -Wframe-larger-than value to avoid instances of that warning with a lower value from the user's configuration. However, with the way that it is currently implemented, it does not respect the user's request via CONFIG_FRAME_WARN for a higher stack frame limit, which can cause pain when new instances of the warning appear and break the build due to CONFIG_WERROR. Adjust the logic to switch from a hard coded -Wframe-larger-than value to only using the value as a minimum clamp and deferring to the requested value from CONFIG_FRAME_WARN if it is higher.

In some cases, these accesses happen via readx_poll_timeout_atomic which ends up timing out, resulting in a warning at hw_atl2_utils_fw.c:112: [ 104.595913] Call Trace: [ 104.595915] <TASK> [ 104.595918] ? show_regs+0x6c/0x80 [ 104.595923] ? __warn+0x8d/0x150 [ 104.595925] ? aq_a2_fw_deinit+0xcf/0xe0 [atlantic] [ 104.595934] ? report_bug+0x182/0x1b0 [ 104.595938] ? handle_bug+0x6e/0xb0 [ 104.595940] ? exc_invalid_op+0x18/0x80 [ 104.595942] ? asm_exc_invalid_op+0x1b/0x20 [ 104.595944] ? aq_a2_fw_deinit+0xcf/0xe0 [atlantic] [ 104.595952] ? aq_a2_fw_deinit+0xcf/0xe0 [atlantic] [ 104.595959] aq_nic_deinit.part.0+0xbd/0xf0 [atlantic] [ 104.595964] aq_nic_deinit+0x17/0x30 [atlantic] [ 104.595970] aq_ndev_close+0x2b/0x40 [atlantic] [ 104.595975] __dev_close_many+0xad/0x160 [ 104.595978] dev_close_many+0x99/0x170 [ 104.595979] unregister_netdevice_many_notify+0x18b/0xb20 [ 104.595981] ? __call_rcu_common+0xcd/0x700 [ 104.595984] unregister_netdevice_queue+0xc6/0x110 [ 104.595986] unregister_netdev+0x1c/0x30 [ 104.595988] aq_pci_remove+0xb1/0xc0 [atlantic] Fix this by skipping firmware deinitialization altogether if the PCI device is no longer present.

2025-02-04gpio: pca953x: Improve interrupt supportMark Tomlinson
The GPIO drivers with latch interrupt support (typically types starting with PCAL) have interrupt status registers to determine which particular inputs have caused an interrupt. Unfortunately there is no atomic operation to read these registers and clear the interrupt. Clearing the interrupt is done by reading the input registers. The code was reading the interrupt status registers, and then reading the input registers. If an input changed between these two events it was lost. The solution in this patch is to revert to the non-latch version of code, i.e. remembering the previous input status, and looking for the changes. This system results in no more I2C transfers, so is no slower. The latch property of the device still means interrupts will still be noticed if the input changes back to its initial state.

2025-02-04accel/amdxdna: Add MODULE_FIRMWARE() declarationsMario Limonciello
Initramfs building tools such as dracut will look for a MODULE_FIRMWARE() declaration to determine which firmware to include in the initramfs when a driver is included in the initramfs. As amdxdna doesn't declare any firmware this causes the driver to fail to load with -ENOENT when in the initramfs. Add the missing declaration for possible firmware.

2025-02-04drm/i915/dp: Iterate DSC BPP from high to low on all platformsJani Nikula
Commit 1c56e9a39833 ("drm/i915/dp: Get optimal link config to have best compressed bpp") tries to find the best compressed bpp for the link. However, it iterates from max to min bpp on display 13+, and from min to max on other platforms. This presumably leads to minimum compressed bpp always being chosen on display 11-12. Iterate from high to low on all platforms to actually use the best possible compressed bpp. Fixes: 1c56e9a39833 ("drm/i915/dp: Get optimal link config to have best compressed bpp") Cc: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Cc: Imre Deak <imre.deak@intel.com> Cc: <stable@vger.kernel.org> # v6.7+ Reviewed-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/3bba67923cbcd13a59d26ef5fa4bb042b13c8a9b.1738327620.git.jani.nikula@intel.com (cherry picked from commit 56b0337d429356c3b9ecc36a03023c8cc856b196) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
