[media] several drivers: Fix a few gcc 4.6 warnings
Mauro Carvalho Chehab [Fri, 11 Mar 2011 19:51:18 +0000 (16:51 -0300)]
au0828-dvb.c:99:6: warning: variable 'ptr' set but not used [-Wunused-but-set-variable]
au0828-video.c:1180:25: warning: variable 'maxheight' set but not used [-Wunused-but-set-variable]
au0828-video.c:1180:15: warning: variable 'maxwidth' set but not used [-Wunused-but-set-variable]
bttv-input.c:196:16: warning: variable 'current_jiffies' set but not used [-Wunused-but-set-variable]

Those variables are not used at all, so just remove them.
