mfd: Switch back to struct platform_driver::remove()

2024-11-01T15:56:58+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/mfd to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. On the way do a few whitespace changes to make indention consistent.

mfd: mcp-sa11x0: Convert to platform remove callback returning void

2023-12-07T13:50:27+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

mfd: mcp-sa11x0: Remove #ifdef guards for PM related functions

2022-12-07T13:28:11+00:00

Use the new pm_sleep_ptr() macro to handle the .suspend/.resume callbacks. This macro allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_SUSPEND is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.

mfd: drop owner assignment from platform_drivers

2013-06-11T17:27:52+00:00

The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han Acked-by: Lee Jones Signed-off-by: Samuel Ortiz
