From 7c018804c0900e7be18507f1eb24e631aa9816ea Mon Sep 17 00:00:00 2001 From: Robert Fitzsimons Date: Wed, 13 Feb 2008 16:38:11 -0300 Subject: [PATCH] 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.
