From: Jingoo Han Date: Tue, 13 May 2014 01:51:58 +0000 (+0900) Subject: i2c: remove unnecessary OOM messages X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=46797a2adbf0cdc3be17707dc64e872eeed86a8a;p=linux-beck.git i2c: remove unnecessary OOM messages The site-specific OOM messages are unnecessary, because they duplicate the MM subsystem generic OOM message. For example, k.alloc and v.alloc failures use dump_stack().
