2018-10-05drm: Remove defunct dma_buf_kmap stubsChris Wilson1-3/+0
Since commit 09ea0dfbf972 ("dma-buf: make map_atomic and map function pointers optional"), we no longer need to provide stub no-op functions as the core now provides them directly.

2017-06-01drm: Extract drm_vblank.[hc]Daniel Vetter1-0/+2
drm_irq.c contains both the irq helper library (optional) and the vblank support (optional, but part of the modeset uapi, and doesn't require the use of the irq helpers at all. Split this up for more clarity of the scope of the individual bits. v2: Move misplaced hunks to this patch (Stefan).

2017-05-08drm/prime: Introduce drm_gem_prime_import_devLaura Abbott1-0/+5
The existing drm_gem_prime_import function uses the underlying struct device of a drm_device for attaching to a dma_buf. Some drivers (notably vgem) may not have an underlying device structure. Offer an alternate function to attach using any available device structure.

2017-03-24drm: drop extern from function declsDaniel Vetter1-15/+15
It's the default storage class for functions, entirely redundant. And a lot of these headers are a bit inconsistent due to organically grown.

2017-03-09drm: Extract drm_file.hDaniel Vetter1-0/+1
I'm torn on whether drm_minor really should be here or somewhere else. Maybe with more clarity after untangling drmP.h more this is easier to decide, for now I've put a FIXME comment right next to it. Right now we need struct drm_minor for the inline drm_file type helpers, and so it does kinda make sense to have them here. Next patch will kerneldoc-ify the entire pile.
