Subject: [PATCH] cifs: fix static checker warning
Git-commit: a9e17d3d74d14e5fd10d54f0a07e0fce4e5f80dd
References: bsc#1193629
Patch-mainline: v6.1-rc1
Remove unnecessary NULL check of oparam->cifs_sb when parsing symlink
error response as it's already set by all smb2_open_file() callers and
deferenced earlier.
This fixes below report:
fs/cifs/smb2file.c:126 smb2_open_file()
warn: variable dereferenced before check 'oparms->cifs_sb' (see line 112)
