Something could have gone wrong because this patch and the patch at http://linuxtv.org/hg/v4l-dvb/rev/659e08177aa3 has the #if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 30) and #endif pair at different places. The current result is the following compiler warning: bttv-i2c.c: In function 'init_bttv_i2c': bttv-i2c.c:440: warning: control reaches end of non-void function Regard, Márton Németh > > This fixes bug #15184: > http://bugzilla.kernel.org/show_bug.cgi?id=15184 > > Signed-off-by: Jean Delvare <kh...@linux-fr.org> > --- > As this fixes a regression, I suggest pushing to Linus quickly.
