[PATCH] usb: dwc2: fix flags for DMA descriptor allocation in dwc2_hsotg_ep_enable

2016-12-01 Thread Marek Szyprowski
dwc2_hsotg_ep_enable can be called from interrupt context, so all allocations should be done with GFP_ATOMIC flags. This fixes following issue on ARM architecture: [] (unwind_backtrace) from [] (show_stack+0x10/0x14) [] (show_stack) from [] (dump_stack+0x74/0x94) [] (dump_stack) from []
