Subject: Btrfs: remove BUG_ON() in btrfs_read_fs_tree_no_radix()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=314297c2a3fbcbda992507f70cd04cc82084e434;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Btrfs: remove BUG_ON() in btrfs_read_fs_tree_no_radix()

We have checked if ->node is NULL or not, so it is unnecessary to
use BUG_ON() to check again. Remove it.
