V4L/DVB (13982): [STV090x] setup master clock in stv090x_init instead of stv090x_setup.
This is needed when clock input is driven from tuner and an output divider different from 1 is used. Signed-off-by: Andreas Regel <andreas.regel@gmx.de> Signed-off-by: Manu Abraham <manu@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
