From f90e160b502fb5c464eb9417ac075a78f13e9801 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Fri, 29 Aug 2014 12:40:55 +0200 Subject: [PATCH] Revert "xhci: Fix number of streams allocated when using streams" This reverts commit d063c3112c4cd23a479ee18720c2bd119da2d315. "2 << x" is the same as "2 ^ (x + 1)", so the old code is correct.
