[media] rtl2832: rename driver state variable from 'priv' to 'dev'
Rename it device state variable to dev. Both priv and dev are very common terms for such variable in kernel, but I like use dev in order to keep drivers consistent. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
