From ae79744975cb0b3b9c469fe1a05db37d2943c863 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Wed, 11 Sep 2013 14:24:10 -0700 Subject: firmware/dmi_scan: drop OOM messages As reported by Joe Perches: OOM messages generally aren't useful. dmi_alloc is either a trivial front-end to kzalloc, and kzalloc already does a dump_stack() when OOM, or for x86, dmi_alloc uses extend_brk which BUGs when unsuccessful. So we can remove all 6 such log messages in the dmi_scan driver, to shrink the binary size (by 528 bytes on x86_64.)
