[PATCH] usb: gadget: pxa27x: Remove redundant assignment to is_short

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Variable 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. Cleans up clang warning:

drivers/usb/gadget/udc/pxa27x_udc.c:1141:2: warning: Value stored
to 'dev' is never read
