Subject: [PATCH] zlib: Mark get_unaligned16() as __maybe_unused
Date: Thu, 18 May 2017 16:46:57 -0700 [thread overview]
Message-ID: <20170518234657.57931-1-mka@chromium.org> (raw)

fixes the following warning when building with clang and
CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS=y:
lib/zlib_inflate/inffast.c:31:1: error: unused function 'get_unaligned16'
[-Werror,-Wunused-function]
get_unaligned16(const unsigned short *p)
