Re: [PATCH v7 1/3] usb: gadget: f_tcm: queue the BOT status requests with GFP_ATOMIC

[Yehyeong Lee]

The ignored usb_ep_queue() return value is pre-existing - it has been that
way since the original c52661d60f63, and this patch only corrects the
allocation flag.  GFP_ATOMIC is required here because bot_send_bad_status()
and bot_send_status() run from the endpoint completion callbacks with
interrupts disabled; GFP_KERNEL was the bug.

Handling a usb_ep_queue() failure (completing the command so the session
does not stall) is a separate, pre-existing issue and would be a follow-up
rather than part of this flag fix.

Thanks,
Yehyeong
