Subject[PATCH 3.10 100/139] usb: r8a66597-hcd: decrease timeout
Date
From: Chris Brandt <chris.brandt@renesas.com>

commit dd14a3e9b92ac6f0918054f9e3477438760a4fa6 upstream.

The timeout for BULK packets was 300ms which is a long time if other
endpoints or devices are waiting for their turn. Changing it to 50ms
greatly increased the overall performance for multi-endpoint devices.
