Patch series "mm: simplify free_highmem_page() and free_reserved_page()". Let's simplify and unify free_highmem_page() and free_reserved_page(). This patch (of 2): This function is never used and it is one of the last remaining user of __free_reserved_page(). Let's just drop it.

2021-02-02amba: Make the remove callback return voidUwe Kleine-König1-3/+1
All amba drivers return 0 in their remove callback. Together with the driver core ignoring the return value anyhow, it doesn't make sense to return a value here. Change the remove prototype to return void, which makes it explicit that returning an error value doesn't work as expected. This simplifies changing the core remove callback to return void, too.

2021-01-13video: omapfb2: Make standard and custom DSI command mode panel driver ↵Sebastian Reichel1-0/+1
mutually exclusive Standard DRM panel driver for DSI command mode panel used by omapfb2 is also available now. Just like the other panels its module name clashes with the module from drivers/video/fbdev/omap2/omapfb/displays, part of the deprecated omapfb2 fbdev driver. As omapfb2 can only be compiled when the omapdrm driver is disabled, and the DRM panel drivers are useless in that case, make the omapfb2 panel depend on the standard DRM panels being disabled to fix the name clash.

The controlfb driver has a number of dummy defines for IO operations. They were introduced in commit a07a63b0e24d ("video: fbdev: controlfb: add COMPILE_TEST support"). The write variants did not use their value parameter in the dummy versions, resulting in set but not used warnings. Fix this by adding "(void)val" to silence the compiler.

2020-12-03powerpc/ps3: make system bus's remove and shutdown callbacks return voidUwe Kleine-König1-3/+1
The driver core ignores the return value of struct device_driver::remove because there is only little that can be done. For the shutdown callback it's ps3_system_bus_shutdown() which ignores the return value. To simplify the quest to make struct device_driver::remove return void, let struct ps3_system_bus_driver::remove return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea and ensures future users behave accordingly.

2020-11-30video: fbdev: aty: Delete unused variable in radeon_monitorSam Ravnborg1-3/+1
Fix warning about variable that is asssigned a value but never used. The variable was indeed never used so delete it. Keep the call to radeon_probe_i2c_connector() as it may have side-effects. It is unlikely but I could not verify that is was safe to drop the call.
