Subject: [PATCH][next] HID: uclogic: remove redudant duplicated null check on ver_ptr
Date: Sat, 2 Mar 2019 22:23:38 +0000 [thread overview]
Message-ID: <20190302222338.8023-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Currently ver_ptr is being null checked twice, once before calling
usb_string and once afterwards. The second null check is redundant
and can be removed, remove it.
Detected by CoverityScan, CID#1477308 ("Logically dead code")
