Paul Mundt 2c940db250 usb: r8a66597-hcd: Fix up spinlock recursion in root hub polling. ... The current root hub polling code exhibits a spinlock recursion on the private controller lock. r8a66597_root_hub_control() is called from r8a66597_timer() which grabs the lock and disables IRQs. The following chain emerges: r8a66597_timer() <-- lock taken r8a66597_root_hub_control() r8a66597_check_syssts() usb_hcd_poll_rh_status() <-- acquires the same lock /* insert death here */ The entire chain requires IRQs to be disabled, so we just unlock and relock around the call to usb_hcd_poll_rh_status() while leaving the IRQ state unchanged.
