[Qemu-devel] [PATCH 04/11] lsi53c895a: avoid a write only variable


From: Blue Swirl
Subject: [Qemu-devel] [PATCH 04/11] lsi53c895a: avoid a write only variable
Date: Wed, 6 Oct 2010 21:32:46 +0000

Compiling with GCC 4.6.0 20100925 produced a warning:
/src/qemu/hw/lsi53c895a.c: In function 'lsi_do_msgout':
/src/qemu/hw/lsi53c895a.c:848:9: error: variable 'len' set but not
used [-Werror=unused-but-set-variable]

Fix by making the variable declaration and its uses also conditional
to debug definition.
