From: Vincent Abriou Date: Tue, 3 Jan 2017 15:06:48 +0000 (+0100) Subject: drm/sti: remove deprecated sti_vtac.c file X-Git-Tag: v4.14-rc1~1422^2~45^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6d10c54a83e214348a2f4d59b103047dc230343c;p=platform%2Fkernel%2Flinux-rpi3.git drm/sti: remove deprecated sti_vtac.c file stih416 chip family is no more supported in Linux v4.9. It is then useless to keep sti_vtac.c file since it not used at all for the stih407/10 chip family supported by sti driver.
