Subject: i2c: Clean up old chip drivers
X-Git-Tag: v2.6.27-rc1~1077^2~2
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f741f673298b03b92d46e30b0b6fd0e960423665;p=pandora-kernel.git

i2c: Clean up old chip drivers

Clean up old i2c chip drivers:
* Name the i2c_client "client" instead of "new_client".
* Drop useless initializations to 0.
