commit 3832374dafb8d0b1b69d8856be28352514afab5d

    drm: update drm.h to latest in drm-next.
    
    This syncs the drm.h header with my drm-next branch as of
    6d61e70ccc21606ffb8a0a03bd3aba24f659502b.
    
    It brings over the semaphore API changes.
    
    Generated using make headers_install.
    Generated from git://people.freedesktop.org/~airlied/linux drm-next commit 6d61e70ccc2.
    
    [airlied: I split patch in two, split reviewed by across both]
