Re: Re: [PATCH 1/6] m88ds3103, montage dvb-s/s2 demodulator driver



2012-04-20 15:56:27 nibble.max@xxxxxxxxx
At first time, I check it exist so try to patch it.
But with new m88ds3103 features to add and ts2022 tuner include, find it is hard to do simply patch.
It is better to create a new driver for maintain.
