[linux-cifs-client] [PATCH] cifs: initialize target_path to NULL in cifs_follow_link

[Jeff Layton]

It's possible for CIFSSMBQueryUnixSymLink to return without setting
target_path to a valid pointer. If that happens then the current
value to which we're initializing this pointer could cause an oops
when it's kfree'd.
