Subject: [PATCH 8/9] ARM: binfmt_flat: unused variable 'persistent'
Date: Tue, 9 Oct 2012 17:23:02 +0200 [thread overview]
Message-ID: <1349796183-30648-9-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1349796183-30648-1-git-send-email-arnd@arndb.de>
The flat_get_addr_from_rp() macro does not use the 'persistent' argument
on ARM, causing a harmless compiler warning. A cast to void removes
that warning.
Without this patch, building at91x40_defconfig results in:
fs/binfmt_flat.c: In function 'load_flat_file':
fs/binfmt_flat.c:746:17: warning: unused variable 'persistent' [-Wunused-variable]
