Subject: f2fs: remove dead code in update_meta_page
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ff95a94dd04cca4b2d5dbeeaaaf1d88b8b4ff1c2;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

f2fs: remove dead code in update_meta_page

After commit a468f0ef516f ("f2fs: use crc and cp version to determine
roll-forward recovery"), last caller of update_meta_page passing @src
with NULL is gone, so remove related dead code there.
