Subject[PATCH][next] HID: uclogic: remove redudant duplicated null check on ver_ptr
Date
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")
