[PATCH 1/1] KERNEL: add __attribute__ in c file

From: Fabian Frederick
Date: Wed May 07 2014 - 16:33:53 EST


This patch fixes a sparse warning about noreturn attribute only
featuring in module.h

kernel/module.c:212:6: error: symbol '__module_put_and_exit' redeclared with
different type (originally declared at include/linux/module.h:449)-
different modifiers
