Hi all,

Changes since 20091127:

The v4l-dvb tree lost its conflict.

on i386 (X86_32):

a 'double' variable is used, causing:

ERROR: "__floatunsidf" [drivers/media/common/tuners/max2165.ko] undefined!
ERROR: "__adddf3" [drivers/media/common/tuners/max2165.ko] undefined!
ERROR: "__fixunsdfsi" [drivers/media/common/tuners/max2165.ko] undefined!

still have this one (above) and similar with
