From d9b33c605c398df1d42c694bda28fe8708754c64 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Thu, 19 Jul 2012 08:51:13 +0300 Subject: usb: dwc3: ep0: split the special cases on ep0_queue We can return early from each if () branch and split the special cases for clarity. While at that also add a comment to the delayed_status case.
