[PATCH] I2C: Kill common macro abuse in chip drivers
This patch kills a common macro abuse in i2c chip drivers: defining ALARMS_FROM_REG returning its argument unchanged. Dropping the macro makes the code somewhat more readable IMHO. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
