From 48a8a03b5806179f12dd6994a6957f797c13675f Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 5 Apr 2013 12:18:54 -0300 Subject: [media] cx88: kernel bz#9476: Fix tone setting for Nova-S+ model 92001 Hauppauge Nova-S-Plus DVB-S model 92001 does not lock on horizontal polarisation. According with the info provided at the BZ, model 92002 does. The difference is that, on model 92001, the tone select is done via isl6421, while, on other devices, this is done via cx24123 code. This patch adds a way to override the demod's set_tone at isl6421 driver. In order to avoid regressions, the override is enabled only for cx88 Nova S plus model 92001. For all other models and devices, the set_tone is provided by the demod driver. Patch originally proposed at bz@9476[1] by Michel Meyers and John Donoghue but applying the original patch would break support for all other devices based on isl6421.
