Subject: btrfs: replace unnecessary list_for_each_entry_safe to list_for_each_entry
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d7641a49a54f66e1a323d0de6b42caeee6d33aa5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

btrfs: replace unnecessary list_for_each_entry_safe to list_for_each_entry

There is no removing list element while iterating over list.
So, replace list_for_each_entry_safe to list_for_each_entry.
