From 571e41214e988bc38c99d804e6d8e1ea1d016342 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Wed, 31 Oct 2012 13:09:07 -0400 Subject: [PATCH] USB: remove iteration limit in hub_tt_work() This patch (as1621) removes the limit on the number of loops allowed in hub_tt_work(). The value is arbitrary, and it's silly to have a limit in the first place -- anything beyond the limit would not get handled. Besides, it's most unlikely that we'll ever need to clear more than a couple of TT buffers at any time.
