Subject: btrfs: Remove unused variable mode in btrfs_mount
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=cebf05ca65d68d0de869a74754e0a0be35056243;p=openwrt%2Fstaging%2Fblogic.git

btrfs: Remove unused variable mode in btrfs_mount

This is a leftover from 312c89fbca06 ("btrfs: cleanup btrfs_mount()
using btrfs_mount_root()"), the mode was used for opening devices that's
not done here anymore.
