drm/savage/savage_bci: Remove set but never used 'aper_rsrc' and 'fb_rsrc'
The comment about them (also removed) says: /* fb_rsrc and aper_rsrc aren't really used currently, but still exist * in case we decide we need information on the BAR for BSD in the * future. */ Well that was written 12 years ago in 2008. We are now in the future and they are still superfluous. We can always add them again at a later date if they are ever required. Fixes the following W=1 kernel build warning(s): drivers/gpu/drm/savage/savage_bci.c: In function ‘savage_driver_firstopen’: drivers/gpu/drm/savage/savage_bci.c:580:24: warning: variable ‘aper_rsrc’ set but not used [-Wunused-but-set-variable] drivers/gpu/drm/savage/savage_bci.c:580:15: warning: variable ‘fb_rsrc’ set but not used [-Wunused-but-set-variable] Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: dri-devel@lists.freedesktop.org Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20201112190039.2785914-2-lee.jones@linaro.org
