Subject: V4L/DVB: ivtv, ivtvfb: Use a define for the output line and field register address Author: Andy Walls <awa...@radix.net> Date: Sat Mar 13 20:37:25 2010 -0300 Get rid of the magic number 0x28c0 used in several places in the ivtv and ivtvfb driver and define the register address to a meaningful name.
