From bdddc253b0938a0063798881d1f6a971ea1d8943 Mon Sep 17 00:00:00 2001 From: Vincent Mailhol Date: Thu, 17 Mar 2022 12:55:14 +0900 Subject: usb: rework usb_maxpacket() using usb_pipe_endpoint() Rework the body of usb_maxpacket() and just rely on the usb_pipe_endpoint() helper function to retrieve the host endpoint instead of doing it by hand.
