Subject: [CIFS] Fix typo in earlier cifs_unlink change and protect one
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=06bcfedd05448e63cae8924074bfacdf82bb17d4;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[CIFS] Fix typo in earlier cifs_unlink change and protect one
extra path.

Since cifs_unlink can also be called from rename path and there
was one report of oops am making the extra check for null inode.
