[PATCH RESEND v2 06/25] drm/fb_helper: Create a wrapper for remove_conflicting_framebuffers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Some drm drivers call remove_conflicting_framebuffers. Create a
drm_fb_helper function that wraps around these calls.

This is part of an effort to prevent drm drivers from calling fbdev
functions directly, in order to make fbdev emulation a top level drm
option.

v2:
- Added kerneldocs
- Follow the drm way of aligning of arguments in func definitions
