-Subject: [PATCH 11/13] usb: musb: Call pm_runtime from musb_gadget_queue
-
-If we're booting pandaboard using NFSroot over built-in g_ether, we
-can get the following after booting once and doing a warm reset:
-
-g_ether gadget: ecm_open
-g_ether gadget: notify connect true
-...
-WARNING: CPU: 0 PID: 1 at drivers/bus/omap_l3_noc.c:147
-l3_interrupt_handler+0x220/0x34c
-44000000.ocp:L3 Custom Error: MASTER MPU TARGET L4CFG (Read):
-Data Access in User mode du ring Functional access
-...
-
-Fix the issue by calling pm_runtime functions from
-musb_gadget_queue.
-
-Note that in the long run we should be able to queue the pending
-transfers if pm_runtime is not active, and flush the queue from
-pm_runtime_resume.
