[2.6 patch] drivers/media/video/cpia_pp.c: convert to module_{init,exit}

From: Adrian Bunk
Date: Sun Mar 25 2007 - 10:58:23 EST


After looking at a section bug (in the non-modular case, clearly
non-init code referenced the __initdata parport_nr[]), I thought it was
time to convert this driver to module_{init,exit}.
