From: Hans de Goede Date: Sun, 11 Jan 2015 19:34:50 +0000 (+0100) Subject: musb-new: Fix interrupt transfers not working X-Git-Tag: v2015.04-rc1~70^2~5 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=e8672e3f0ec571d0ca7ccd8cbbeb113802c1d443;p=u-boot 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.
