Subject: dm crypt: tidy pending
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=80fd662683be5dc2a3b41b27e30942d5fd7b5d5c;p=openwrt%2Fstaging%2Fblogic.git

dm crypt: tidy pending

Add crypt prefix to dec_pending to avoid confusing it in backtraces with
the dm core function of the same name.

No functional change here.
