| Message-ID | <tU6D7-4lE-1@gated-at.bofh.it> |
4.11-stable review patch. If anyone has any objections, please let me know.
------------------
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.
