Subject: [PATCH] dtc: Remove unused variable in flat_read_mem_reserve
Date: Tue, 28 Jun 2011 09:42:53 -0400 [thread overview]
Message-ID: <20110628134253.GD10237@zod.rchland.ibm.com> (raw)
The *p variable is declared and used to save inb->ptr, however p is
later never used. This has been the case since commit 6c0f3676 and can
lead to build failures with -Werror=unused-but-set-variable:
flattree.c: In function 'flat_read_mem_reserve':
flattree.c:700:14: error: variable 'p' set but not used [-Werror=unused-but-set-variable]
cc1: all warnings being treated as errors
make: *** [flattree.o] Error 1
Remove the variable.
