Subject: [PATCH] usb: storage: freecom: drop useless assignment in init_freecom()
Date: Wed, 29 Nov 2023 23:43:50 +0300	[thread overview]
Message-ID: <4d3fb70f-bf2f-96cc-a8fb-1ef658a24920@omp.ru> (raw)

In init_freecom(), the results of usb_stor_control_msg() calls are stored
in the local variable and then printed out by usb_stor_dbg() (if enabled),
except for the 1st call, the result of which is completely ignored.  Drop
the useless assignment.

Found by Linux Verification Center (linuxtesting.org) with the Svace static
analysis tool.
