[PATCH v4 02/10] usb: gadget: change len to size_t on alloc_ep_req()

From: Felipe F. Tonello
Date: Mon Aug 08 2016 - 16:32:51 EST


Length of buffers should be of type size_t whenever possible. Altough
recommended, this change has no real practical change, unless a driver has a
uses a huge or negative buffer size - it might help find these bugs.
