Subject: uhci: renumber uhci_handle_td return codes
X-Git-Tag: v1.1-rc0~235^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=0cd178ca2cabf94e7acaa64eca6714f966edaa0d;p=thirdparty%2Fqemu.git

uhci: renumber uhci_handle_td return codes

Step #2 (separate for better bisectability): renumber so the silly '-1'
goes away.  Pick a range which doesn't overlap the old values.
