[PATCH] mmc: queue: add #ifdef around bounce buffer code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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()")
