From: Lin Wang Date: Fri, 9 Jan 2015 14:06:28 +0000 (+0200) Subject: xhci: remove unused parameter 'xhci' in function xhci_handshake(). X-Git-Tag: firefly_0821_release~176^2~2323^2~77 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=dc0b177cf8be1e7371cfb92cfbccac595bf8dac8;p=firefly-linux-kernel-4.4.55.git xhci: remove unused parameter 'xhci' in function xhci_handshake(). Parameter 'xhci' is no longer be used in function xhci_handshake(), just remove it.
