[Qemu-devel] [PATCH 06/14] usb-linux: We only need to keep track of 15 endpoints |
Date: |
Wed, 4 May 2011 17:41:40 +0200 |
From: Hans de Goede <address@hidden>
Currently we reserve room for endpoint data for 16 endpoints, but given
that we only use endpoint data for endpoints 1-15, and always index the
array with the endpoint-number - 1, 15 is enough.
