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
