usb: fixes for v3.7-rc2
Here's the first set of fixes for v3.7-rc cycle.
DesignWare Core USB3 Driver (dwc3) got two fixes. The first one fixes a long
standing bug which would keep endpoint with BUSY flag set forever if we cancel
a transfer which has already been started by the controller. The second fix
will just switch PHYs back off when DWC3 driver is removed.
MUSB fixed a bug which would cause a Kernel Oops at least on AM3517 when
removing a device. For some reason that particular device can fall into a
situation where you have both Disconnect and Endpoint IRQs happen
simultaneously (have both bits set in IRQ_STATUS register) and, because
Disconnect Interrupt is handled before Endpoint Interrupts, we would try to
transfer data over a disconnected device, thus generating a kernel oops.
Renensas' USB DRD driver got two fixes which are a) fixing an off-by-one bug on
the pipe iterator implementation and b) fixing Interrupt Status Clear procedure
in order to properly clear a single Interrupt event without clearing (and
masking) other events we didn't handle yet.
