backlight: bd6107: Convert to i2c's .probe_new()

2022-12-07T13:33:02+00:00

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Reviewed-by: Daniel Thompson Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20221118224540.619276-589-uwe@kleine-koenig.org

i2c: Make remove callback return void

2022-08-16T10:46:26+00:00

The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

backlight: Use backlight_get_brightness() throughout

2020-07-20T09:27:06+00:00

Introduce the backlight_get_brightness() helper in all video/backlight/* drivers. This simplifies the code and align the implementation of the update_status() operation across the different backlight drivers. Some of the drivers gains a little extra functionality by the change as they now respect the fb_blank() ioctl. Signed-off-by: Sam Ravnborg Reviewed-by: Daniel Thompson Signed-off-by: Lee Jones

backlight: bd6107: Convert to use GPIO descriptor

2019-12-16T10:32:27+00:00

The Rohm BD6107 driver can pass a fixed GPIO line using the old GPIO API using platform data. As there are no in-tree users of this platform data since 2013, we can convert this to use a GPIO descriptor and require any out-of-tree consumers to pass the GPIO using a machine descriptor table instead.
