Subject: fs/btrfs/inode.c: remove unnecessary new_valid_dev() check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7cac0a85992229a631d4e01934d2e1c042566189;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

fs/btrfs/inode.c: remove unnecessary new_valid_dev() check

new_valid_dev() always returns 1, so the !new_valid_dev() check is not
needed.  Remove it.
