From: xiao jin Date: Fri, 11 Oct 2013 00:57:03 +0000 (+0800) Subject: xhci: correct the usage of USB_CTRL_SET_TIMEOUT X-Git-Tag: next-20131021~29^2~9^2~20 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d194c031994d3fc1038fa09e9e92d9be24a21921;p=karo-tx-linux.git xhci: correct the usage of USB_CTRL_SET_TIMEOUT The usage of USB_CTRL_SET_TIMEOUT in xhci is incorrect. The definition of USB_CTRL_SET_TIMEOUT is 5000ms. The input timeout to wait_for_completion_interruptible_timeout is jiffies. That makes the timeout be longer than what we want, such as 50s in some platform. The patch is to use XHCI_CMD_DEFAULT_TIMEOUT instead of USB_CTRL_SET_TIMEOUT as command completion event timeout.
