Subject: [Patch] kbuild: fix a compile warning
Date: Fri, 15 May 2009 03:51:18 -0400 [thread overview]
Message-ID: <20090515075229.11346.6710.sendpatchset@localhost.localdomain> (raw)
I got this warning:
HOSTCC scripts/basic/fixdep
scripts/basic/fixdep.c: In function 'traps':
scripts/basic/fixdep.c:377: warning: dereferencing type-punned pointer will break strict-aliasing rules
scripts/basic/fixdep.c:379: warning: dereferencing type-punned pointer will break strict-aliasing rules
Patch below fixes it.
