Subject: mtd: ubi: Remove unused ubi_flush
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ca7be9c0a148cbfe38df95a0285339c532ca6e17;p=thirdparty%2Fkernel%2Flinux.git

mtd: ubi: Remove unused ubi_flush

ubi_flush() was added in 2012 as part of
commit 62f384552b67 ("UBI: modify ubi_wl_flush function to clear work queue
for a lnum")
but has remained unused.

(It's friend ubi_wl_flush() is still used)

Remove it.
