usb: gadget: pxa27x: Remove redundant assignment to is_short and dev
Variable is_short is set to zero but this value is never read as it is
overwritten with a new value later on, hence it is a redundant
assignment and can be removed. Pointer dev is assigned a value that
is not read and it is updated a few statements later, this too is
redundant and can be removed. Cleans up clan warnings:
drivers/usb/gadget/udc/pxa27x_udc.c:986:3: warning: Value stored
to 'is_short' is never read
drivers/usb/gadget/udc/pxa27x_udc.c:1141:2: warning: Value stored
to 'dev' is never read
