drm/sti: Add __iomem for mixer_dbg_mxn's parameter

2024-12-14T18:59:48+00:00

[ Upstream commit 86e8f94789dd6f3e705bfa821e1e416f97a2f863 ] Sparse complains about incorrect type in argument 1. expected void const volatile __iomem *ptr but got void *. so modify mixer_dbg_mxn's addr parameter.

drm: Explicitly include correct DT includes

2023-07-21T07:12:43+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

drm/sti: Convert to platform remove callback returning void

2023-06-08T16:04:12+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 (mostly) ignored 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. Trivially convert the sti drm drivers from always returning zero in the remove callback to the void returning variant.

drm: Drop ARCH_MULTIPLATFORM from dependencies

2023-03-14T11:57:22+00:00

Some of these dependencies used to be sensible when only a small part of the platforms supported by ARCH=arm could be compiled together in a single kernel image. Nowadays ARCH_MULTIPLATFORM is only used as a guard for kernel options incompatible with a multiplatform image. See commit 84fc86360623 ("ARM: make ARCH_MULTIPLATFORM user-visible") for some more details.
