[PATCH] USB: remove iteration limit in hub_tt_work()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
