Subject: [PATCH] mmc: Fix warning if debug() is not used
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
If debug() is not used, then the whole content of debug(...) will
be removed by the preprocessor, which will result in the following
warning. This patch adds __maybe_unused annotation to fix this.
drivers/mmc/mmc.c: In function âmmc_initâ:
drivers/mmc/mmc.c:1685:11: warning: variable âstartâ set but not used [-Wunused-but-set-variable]
unsigned start;
