Subject: V4L/DVB (6127): tuner: kill i2c_client interface to tuner sub-drivers
X-Git-Tag: v2.6.24-rc1~1463^2~144
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=db8a695658cda21eacfa2a5e3b15e8964bfb93ef;p=linux-2.6

V4L/DVB (6127): tuner: kill i2c_client interface to tuner sub-drivers

To ease the conversion of the analog tuner sub-drivers into dvb_frontend
style tuner modules, we must remove the i2c_client interface.

dvb_frontend style tuner modules use i2c_transfer directly on the i2c_adapter.

This change only alters the interface between tuner.ko and the tuner
sub-drivers. The v4l2 / i2c_client interface to tuner.ko remains intact.

This patch adds inline functions tuner_i2c_xfer_send, and tuner_i2c_xfer_recv,
to replace i2c_master_send and i2c_master_recv inside the tuner sub-drivers.
