Subject: [PATCH v1 3/4] usb: usb-uclass.c: Drop le16_to_cpu() as values are already swapped
Date: Thu, 2 Jul 2020 10:47:32 +0200 [thread overview]
Message-ID: <20200702084733.2032531-4-sr@denx.de> (raw)
In-Reply-To: <20200702084733.2032531-1-sr@denx.de>
These values are already swapped to CPU endianess, so swapping them
again is a bug. Let's remove the swap here instead.
