Subject: [PATCH 2/3] usb: storage: Default to a single LUN
Date: Wed, 22 May 2019 00:33:48 -0700	[thread overview]
Message-ID: <20190522073349.9004-2-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190522073349.9004-1-andrew.smirnov@gmail.com>

For loop below is:

	for (lun=0; lun<=us->max_lun; lun++)
	    ...

so we need to set max_lun to 0 in order to default to having only one
LUN. Otherwise, we end up assuming the device has 2 valid LUNs.
