From fab4655990012268e82f830d04e743905fb9ba3d Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Mon, 24 Oct 2022 17:23:43 +0200 Subject: [PATCH] media: stv0288: use explicitly signed char commit 7392134428c92a4cb541bd5c8f4f5c8d2e88364d upstream. With char becoming unsigned by default, and with `char` alone being ambiguous and based on architecture, signed chars need to be marked explicitly as such. Use `s8` and `u8` types here, since that's what surrounding code does. This fixes: drivers/media/dvb-frontends/stv0288.c:471 stv0288_set_frontend() warn: assigning (-9) to unsigned variable 'tm' drivers/media/dvb-frontends/stv0288.c:471 stv0288_set_frontend() warn: we never enter this loop Cc: Mauro Carvalho Chehab Cc: linux-media@vger.kernel.org Cc: stable@vger.kernel.org Signed-off-by: Jason A.
