VIA_WAIT_ON() is a direct copy of DRM_WAIT_ON() from drm_os_linux.h. The copy is made so we can avoid the dependency on the legacy header. A more involved approach had been to introduce wait_event_* but for this legacy driver the simpler and more safe approach with a copy of the macro was selected. Added the relevant header files for the functions used in VIA_WAIT_ON. v3: - Updated users of DRM_WAIT_ON => VIA_WAIT_ON (Emil) - Updated $subject (Emil) Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Cc: Kevin Brace <kevinbrace@gmx.com> Cc: Thomas Hellstrom <thellstrom@vmware.com> Cc: "Gustavo A.
