From f8e40c64095cef74bb5b1ab3f382a4f8d88975aa Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 13 Feb 2008 16:38:11 +0000 Subject: bttv: Fix overlay divide error. From: Robert Fitzsimons 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.
