X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e41128cfd9389b889e91097b8ca61574d1e71482;p=openwrt%2Fstaging%2Fblogic.git

block: remove set but not used variable 'et'

Fixes gcc '-Wunused-but-set-variable' warning:

block/blk-ioc.c: In function 'put_io_context_active':
block/blk-ioc.c:174:24: warning:
 variable 'et' set but not used [-Wunused-but-set-variable]

It not used any more after commit
