    NFC: nfcmrvl: use nfc-device for firmware download · e5834ac2
    Johan Hovold authored
    Use the nfc- rather than phy-device in firmware-management code that
    needs a valid struct device.
    This specifically fixes a NULL-pointer dereference in
    nfcmrvl_fw_dnld_init() during registration when the underlying tty is
    one end of a Unix98 pty.
    Note that the driver still uses the phy device for any debugging, which
    is fine for now.
    Fixes: 3194c687 ("NFC: nfcmrvl: add firmware download support")
