Subject: [PATCH] mmc: queue: add #ifdef around bounce buffer code
Date: Wed, 30 Nov 2016 22:03:59 +0100 [thread overview]
Message-ID: <20161130210427.1721327-1-arnd@arndb.de> (raw)
The two functions that got split out from the bounce
buffer handling are now unused when CONFIG_MMC_BLOCK_BOUNCE
is disabled:
mmc/card/queue.c:212:12: error: 'mmc_queue_alloc_bounce_sgs' defined but not used [-Werror=unused-function]
mmc/card/queue.c:189:13: error: 'mmc_queue_alloc_bounce_bufs' defined but not used [-Werror=unused-function]
This adds a new #ifdef around them.
Fixes: 0a6321310492 ("mmc: queue: Factor out mmc_queue_alloc_bounce_bufs()")
