From 80142efa715581c06d01b37f299a240309699ff4 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 14 Jun 2009 06:26:49 -0300 Subject: [PATCH] V4L/DVB (12077): gspca_ov519: Fix 320x240 with ov7660 sensor As reported on the ov51x-jpeg list, and as I can confirm with my own cam the ov7670 in 320x240 has a number of broken columns of pixels at the left of the picture. This was not present in the old driver as it always used 640x480 and did software downscaling (took me a while to figure that one out). The fix adds a sensor specific if in so far sensor neutral code :( But this is the only way to fix this, this cannot be fixed by only changing sensor registers.
