Subject: fs/ntfs3: Remove a useless test
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=548744f84456946181ed6dc0ac6be8267f167d28;p=linux.git

fs/ntfs3: Remove a useless test

'new_free' has just been allocated by kmalloc() and is known to be not
NULL.
So this pointer can't be equal to a previous memory allocation.
