Subject: [PATCH] media: stv0288: use explicitly signed char
Date: Mon, 24 Oct 2022 18:27:56 +0200 [thread overview]
Message-ID: <20221024162756.535776-1-Jason@zx2c4.com> (raw)
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
