Subject: [Qemu-devel] [PULL 05/17] Revert "xhci: Fix number of streams allocated when using streams"
Date: Fri, 29 Aug 2014 14:03:40 +0200 [thread overview]
Message-ID: <1409313832-2514-6-git-send-email-kraxel@redhat.com> (raw)
In-Reply-To: <1409313832-2514-1-git-send-email-kraxel@redhat.com>
This reverts commit d063c3112c4cd23a479ee18720c2bd119da2d315.
"2 << x" is the same as "2 ^ (x + 1)", so the old code is correct.
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
