This reverts commit ade7de160bffe8381c7cf616da24bbc8f5efc916.
vdr-addon: re-add pull/2256
linux: re-add (horrible adapted) linux-210-dvbsky.patch
linux-tbs-drivers: update to linux-tbs-drivers-130429

this is a dirty workaround, because it seems like tbs can't do it right. again

in linux tbs driver changelog I see:

2. XXXXXX Linux Driver is updated to v130429, which has below updating
* Further improve Linux kernel 3.9.x compatibility.

which is, in fact, not true, after quick diff I realized
that they changed exactly nothing.

next time tbs should do their job, instead of announcing support for 'kernel xxx'
why would we support this driver in the future ? it's not our job to fix broken drivers now and then.
