Btrfs: kmalloc() doesn't return an ERR_PTR
The error handling was copy and pasted from memdup_user(). It should be checking for NULL obviously. Fixes: abccd00f8af2 ('btrfs: Fix 32/64-bit problem with BTRFS_SET_RECEIVED_SUBVOL ioctl') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Chris Mason <clm@fb.com>
