[media] gspca: Add jl2005bcd sub driver
Theodore Kilgore [Tue, 13 Dec 2011 21:09:15 +0000 (18:09 -0300)]
Written by Theodore Kilgore

With minor changes by Hans de Goede:
-Code style fixes
-Correct the verbose level on various PDEBUG messages
-Make error messages use pr_err instead of PDEBUG
-Document the jl20 pixel format
