devfreq: Use sysfs_emit() for cpumask show callbacks

2026-07-07T18:32:25+00:00

These callbacks are sysfs show paths. Use sysfs_emit() and cpumask_pr_args() to emit the masks. This prepares for removing cpumap_print_to_pagebuf(). Signed-off-by: Yury Norov

Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

devfreq: change devfreq_event_class to a const struct

2026-05-22T11:28:46+00:00

The class_create() call has been deprecated in favor of class_register() as the driver core now allows for a struct class to be in read-only memory. Change devfreq_event_class to be a const struct class and drop the class_create() call. Compile tested.

PM / devfreq: Fix governor_store() failing when device has no current governor

2026-05-10T12:53:44+00:00

Since devfreq_remove_governor() may clear the device's current governor in certain situations, while governors actually exist independently of the device, directly returning EINVAL in this case is inaccurate. To fix this issue, remove this check and add relevant logic for when df->governor is NULL.

PM / devfreq: event: rockchip-dfi: Fix missing clk_disable_unprepare() on error

2026-04-29T22:38:34+00:00

Smatch reports: drivers/devfreq/event/rockchip-dfi.c:215 rockchip_dfi_enable() warn: 'dfi->clk' from clk_prepare_enable() not released. If rockchip_dfi_ddrtype_to_ctrl() fails after clk_prepare_enable(), the clock is not disabled, leading to a resource leak. Add clk_disable_unprepare() in the error path to properly release the clock.

PM / devfreq: Optimize error return value of governor_show()

2026-04-29T22:06:44+00:00

When df->governor is NULL, governor_show() returns -EINVAL, which confuses users. To fix this issue, return -ENOENT to indicate that no governor is currently set for the device.

PM / devfreq: Fix available_governors_show() when no governor is set

Since devfreq_remove_governor() may clear the device's current governor in certain situations, while governors actually exist independently of the device, directly returning EINVAL in this case is inaccurate. To fix this issue, remove this check and use df->governor for validity verification in the following code.
