[PATCH v2 0/2] USB: EHCI: Allow users to override 80% max periodic bandwidth

[Kirill Smelkov <kirr@mns.spb.ru>]

Changes since v1:


 - dropped RFC status as "this seems like the sort of feature somebody might
   reasonably want to use -- if they know exactly what they're doing";

 - new preparatory patch (1/2) which moves already-in-there sysfs code into
   ehci-sysfs.c;

 - moved uframe_periodic_max parameter from module option to sysfs attribute,
   so that it can be set per controller and at runtime, added validity checks;

 - clarified a bit bandwith analysis for 96% max periodic setup as noticed by
   Alan Stern;

 - clarified patch description saying that set in stone 80% max periodic is
   specified by USB 2.0;
