Subject: [patch] usb: gadget: precedence bug in show_requests()
Date: Sun, 20 Jan 2013 14:50:44 +0000 [thread overview]
Message-ID: <20130120145044.GA32551@elgon.mountain> (raw)
The mod operation has higher precedence than the divide but the intent
was to divide first. It's supposed to count through one time for RX
and a second time for TX but instead of doing "0 1 2 0 1 2" it does
"0 0 1 1 2 2".
