Input: regulator-haptic - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2023-01-10T04:25:22+00:00

SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection against unused function warnings. The new combination of pm_sleep_ptr() and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the __maybe_unused markings.

locking/atomics: COCCINELLE/treewide: Convert trivial ACCESS_ONCE() patterns to READ_ONCE()/WRITE_ONCE()

2017-10-25T09:01:08+00:00

Please do not apply this to mainline directly, instead please re-run the coccinelle script shown below and apply its output. For several reasons, it is desirable to use {READ,WRITE}_ONCE() in preference to ACCESS_ONCE(), and new code is expected to use one of the former. So far, there's been no reason to change most existing uses of ACCESS_ONCE(), as these aren't harmful, and changing them results in churn. However, for some features, the read/write distinction is critical to correct operation. To distinguish these cases, separate read/write accessors must be used. This patch migrates (most) remaining ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following coccinelle script: ---- // Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and // WRITE_ONCE() // $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch virtual patch @ depends on patch @ expression E1, E2; @@ - ACCESS_ONCE(E1) = E2 + WRITE_ONCE(E1, E2) @ depends on patch @ expression E; @@ - ACCESS_ONCE(E) + READ_ONCE(E) ---- Signed-off-by: Mark Rutland Signed-off-by: Paul E.

Input: regulator-haptic - fix module autoload for OF platform driver

2015-09-03T17:56:20+00:00

This platform driver has a OF device ID table but the OF module alias information is not created so module autoloading won't work. Signed-off-by: Luis de Bethencourt Signed-off-by: Dmitry Torokhov

Input: constify of_device_id arrays

of_device_id is always used as const argument (See driver.of_match_table and open firmware functions). Signed-off-by: Fabian Frederick Signed-off-by: Dmitry Torokhov

Input: regulator-haptic - simplify code

2015-01-11T23:52:59+00:00

All the use cases in this driver has a regulator_haptic_toggle() call after regulator_haptic_set_voltage(). So make regulator_haptic_set_voltage() call regulator_haptic_toggle() to simplify the code. Signed-off-by: Axel Lin Signed-off-by: Dmitry Torokhov

Input: add regulator haptic driver

2014-12-22T02:59:20+00:00

This change adds support for haptic driver controlled by voltage of a regulator. Userspace can control the device via Force Feedback interface from input framework.
