| H A D | drm_gem_framebuffer_helper.h | 37408cd8 Fri Jul 16 14:07:55 GMT 2021 Thomas Zimmermann <tzimmermann@suse.de> drm/gem: Provide drm_gem_fb_{begin,end}_cpu_access() helpers
Implement helpers drm_gem_fb_begin_cpu_access() and _end_cpu_access(),
which call the rsp dma-buf functions for all GEM BOs of the given
framebuffer.
Calls to dma_buf_end_cpu_access() can return an error code on failure,
while drm_gem_fb_end_cpu_access() does not. The latter runs during DRM's
atomic commit or during cleanup. Both cases don't allow for errors, so
leave out the return value.
v2:
* fix typo in docs (Daniel)
