Subject: [PATCH] usb: gadget: udc:  remove redundant initial assignments to the pointer 's'

From: Colin Ian King <colin.king@...onical.com>

The initial setting of pointer s to the driver name or to the literal
string "(none)" is redundant as later it is always set to point to
a different literal string before it is printed log.  Remove this
redundant code.

Detected with CoverityScan, CID#1227032, CID#1227033 ("Unused Value")
