V4L/DVB (7197): bttv: Fix overlay divide error
The initial work to convert the bttv driver to V4L2 "Partial conversion from V4L1 to V4L2" (e84619b17440ccca4e4db7583d126c4189b987e5), missed the line which set the appropriate overlay crop structure in the newly allocated bttv_buffer. This then causes a divide error in the bttv_calc_geo function. Signed-off-by: Robert Fitzsimons <robfitz@273k.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
