From: Antti Palosaari Date: Fri, 17 Apr 2015 00:36:00 +0000 (-0300) Subject: [media] m88ds3103: rename variables and correct logging X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7978b8a1bc8ae0f2aea1e4f36ef7642a1b86b9c6;p=linux-beck.git [media] m88ds3103: rename variables and correct logging Rename driver state from priv to dev. Use I2C client for correct logging. Use adapter and address from I2C client structure where needed.
