drm: IRQ midlayer is now legacy

2021-08-10T18:14:01+00:00

Hide the DRM midlayer behind CONFIG_DRM_LEGACY, make functions use
the prefix drm_legacy_, and move declarations to drm_legacy.h.
In struct drm_device, move the fields irq and irq_enabled behind
CONFIG_DRM_LEGACY.

All callers have been updated.

drm: Mark AGP implementation and ioctls as legacy

2021-05-10T13:46:58+00:00

Only UMs drivers use DRM's core AGP code and ioctls. Mark the icotls
as legacy. Add the _legacy_ infix to all AGP functions. Move the
declarations to the public and internal legacy header files. The agp
field in struct drm_device is now located in the structure's legacy
section. Adapt drivers to the changes.

AGP code now depends on CONFIG_DRM_LEGACY.

drm/via: Fix fall-through warnings for Clang

2020-11-22T21:58:55+00:00

In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning
by explicitly adding a break statement instead of letting the code fall
through to the next case.

In function via_mem_alloc`s error branch, DRM_ERROR is protected
in the mutex_lock(&dev->struct_mutex) area.
>From the code, we see that DRM_ERROR is just an error log print
