3.16.44-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
commit 453785c64e090d9b4169636b7276fcd6d7489d33 upstream.
The 2nd check for a non-zero return from copy_to_user is redundant as
it is has already been made a few lines earlier. This check was made
redundant because of previous fix to the copy_to_user error return
check.
Detected by CoverityScan, CID#114347 ("Logically Dead Code")
Fixes: 1865a9c382ede ("USB: adutux: fix misuse of return value of copy_to_user()")
