Re: [PATCH] DVB: lgdt330x frontend: some bug fixes & add lgdt3303 support

[Mauro Carvalho Chehab <mchehab@brturbo.com.br>]

	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.
