usb: fixes for v4.0-rc2 

Not that many fixes this time. They have all been tested on
 platforms I have around and also passed my randconfig builds.
 
 Here's a quick summary of the changes:
 
 Phonet function learned to not disable a disabled endpoint.
 
 musb received a pm_runtime_irq_safe() call to fix a bug when
 calling musb_pullup() (via usb_gadget_{connect,disconnect}())
 with irqs disabled.
 
 musb also got a really old fix for throughput with isochronous
 endpoints by pushing URB completion to a tasklet (by means of
 HCD_BH flag).
 
 musb now can properly get its phys on musb-dsps platforms (am335x
 as of now).
 
 musb learned how to read boolean OF properties.
 
 Old bug on how to disable dwc3-omap's IRQs got fixed finally.
 
 A few sparse warnings here and there.
 
 Renesas got a linkage fix.

Not that many fixes this time. They have all been tested on

Here's a quick summary of the changes:

Phonet function learned to not disable a disabled endpoint.

musb received a pm_runtime_irq_safe() call to fix a bug when
calling musb_pullup() (via usb_gadget_{connect,disconnect}())
with irqs disabled.

musb also got a really old fix for throughput with isochronous
endpoints by pushing URB completion to a tasklet (by means of
HCD_BH flag).

musb now can properly get its phys on musb-dsps platforms (am335x
as of now).

musb learned how to read boolean OF properties.

Old bug on how to disable dwc3-omap's IRQs got fixed finally.

A few sparse warnings here and there.

Renesas got a linkage fix.
