From bf51a8c5e0b6133b929eb7d7456e99a605f8168c Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sat, 9 Mar 2013 08:16:46 +0000 Subject: i2c: Ignore return value of i2c_del_adapter() i2c_del_adapter() always returns 0. So all checks testing whether it will be non zero will always evaluate to false and the conditional code is dead code. This patch updates all callers of i2c_del_mux_adapter() to ignore the return value and assume that it will always succeed (which it will). In a subsequent patch the return type of i2c_del_adapter() will be made void.
