Subject: i2c: rk3x: report number of messages transmitted
From: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx>
commit c6cbfb91b878224e78408a2e15901c79de77115a upstream.
master_xfer() method should return number of i2c messages transferred,
but on Rockchip we were usually returning just 1, which caused trouble
with users that actually check number of transferred messages vs.
checking for negative error codes.
