From d0dd962d8a4ef4df9b710c4e3a975e6bfd9f0225 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 28 May 2018 10:32:41 -0400 Subject: [PATCH] media: dvb: get rid of VIDEO_SET_SPU_PALETTE No upstream drivers use it. It doesn't make any sense to have a compat32 code for something that nobody uses upstream.
