Subject: [media] smiapp: Remove unused quirk register functionality
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d4f79a80e6024b8dc50d4d3275dc4ed08729bb95;p=linux-beck.git

[media] smiapp: Remove unused quirk register functionality

The quirk registers mechanism which allows register to have a static read
access value from the sensor specific quirks, is not used. Remove it. It is
to be replaced by a more generic register diversion quirk soon.
