From e8672e3f0ec571d0ca7ccd8cbbeb113802c1d443 Mon Sep 17 00:00:00 2001 From: Hans de Goede <hdegoede@redhat.com> Date: Sun, 11 Jan 2015 20:34:50 +0100 Subject: [PATCH] musb-new: Fix interrupt transfers not working For bulk and ctrl transfers common/usb.c sets udev->status = USB_ST_NOT_PROC, but it does not do so for interrupt transfers. musb_uboot.c: submit_urb() however was waiting for USB_ST_NOT_PROC to become 0, and thus without anyone setting USB_ST_NOT_PROC would exit immediately for interrupt urbs, returning the urb status of EINPROGRESS as error. This commit fixes this, thereby also making usb_kbd.c work together with musb_new and CONFIG_SYS_USB_EVENT_POLL.
