Subject: [U-Boot] [PATCH v1 1/4] usb: ether: call _usb_eth_halt() if initialization fails
Date: Tue, 22 Jan 2019 23:37:10 +0100	[thread overview]
Message-ID: <20190122233710.5a386877@jawa> (raw)
In-Reply-To: <20190122154819.3171-2-jjhiblot@ti.com>

Hi Jean-Jacques,

> If the host does not respond in time, the initialization fails.
> However the usb ether driver will still be registered. This will make
> usb_gadget_probe_driver() fail the next time the initialization is
> attempted because it cannot find an available UDC.
> 
> Fixing this by calling _usb_eth_halt() when the init fails.
