Subject: [PATCH v2 0/2] Disable mass storage endpoints during disconnect
Date: Tue, 26 Oct 2021 19:50:23 -0700 [thread overview]
Message-ID: <1635303025-772-1-git-send-email-quic_wcheng@quicinc.com> (raw)
Changes in v2:
- Revised comments for usb_ep_disable() as it should be safe to be
executed in atomic contexts as well. Other FDs are currently
calling ep disable during the disconnect event as well.
This series calls the usb_ep_disable() API directly from fsg_disable()
as there is a possibility that UDCs that support runtime PM may
already be in a suspended state, leading to HW access while resources
are disabled.
