Regardless, the patch must be applied.  The above should only break with DVB_FE_CUSTOMIZE=Y ...

Turn off DVB_FE_CUSTOMIZE, and you will find that the above does NOT break.  You can probably reproduce this 'broken' situation by setting any card driver = y, with the frontend = m ...

As stated in the prior thread, "CONFIG_VIDEO_SAA7134_DVB=y, CONFIG_DVB_TDA826X=m" is not the problem -- rather, "CONFIG_VIDEO_SAA7134_DVB=y, CONFIG_DVB_TDA826X=m, DVB_FE_CUSTOMIZE=Y" causes the breakage.
