Subject: [media] drxk: Move I2C address into a config structure
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0fc55e81d3364e6535cacb10b5a579f8c62625b1;p=mv-sheeva.git

[media] drxk: Move I2C address into a config structure

Currently, the only parameter to be configured is the I2C
address. However, Terratec H5 logs shows that it needs a different
setting for some things, and it has its own firmware.

So, move the addr into a config structure, in order to allow adding
the required configuration bits.
