Subject: usb: ohci: Remove unused devgone global variable
X-Git-Tag: accepted/tizen/common/20150522.093834~98^2~13
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=69710ce3ee73445f1c445c41a853fd1d08acd5d1;p=platform%2Fkernel%2Fu-boot.git

usb: ohci: Remove unused devgone global variable

devgone is never assigned a value, so the one comparisson reading it will
never be true, and devgone can be completely removed.
