Subject: block: don't duplicate mounting code in the mount_device()
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=a778468bca43a269d80b31b5d7b96bf745a00f38;p=oweals%2Ffstools.git

block: don't duplicate mounting code in the mount_device()

Once target directory gets specified mounting code is identical for
devices having and not having UCI config entry. Share it.
