    SubjectRe: [PATCH] DVB: lgdt330x frontend: some bug fixes & add lgdt3303 support
    From
    Date
    	This should't be applied to 2.6.13. It does contain a hack at V4L code,
    since mute_tda9887 is implemented outside tda9887.c module and could
    potentially cause troubles since there are some work to provide it on a
    correct way.
    It should be applied to -mm and go to mainstream only after provided a
    correct implementation.

    Mkrufky,
    Please avoid trying to submit yet experimental patches to mainstream.

    Mauro.
