USB HCD: avoid duplicate local_irq_disable()
Arnd Bergmann wrote:
usb_hcd_flush_endpoint() has a retry loop that starts with a spin_lock_irq(),
but only gives up the spinlock, not the irq_disable before jumping to the
rescan label.
Alan Stern:
I agree with your sentiment, but it would be better to solve this
problem without using local_irq_disable().
