Tonello" Date: Mon, 8 Aug 2016 21:30:05 +0100 Subject: usb: gadget: change len to size_t on alloc_ep_req() From: Felipe F. Tonello commit 69bb99738b5c6d56d2b1a75db9cbb4d187453c1a upstream. 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. Signed-off-by: Felipe F.
