From dffa51cf2d3f5bcbc5cf4471b9f4dfbf2ef3c810 Mon Sep 17 00:00:00 2001 From: Prashanth K Date: Tue, 22 Apr 2025 16:02:29 +0530 Subject: [PATCH] usb: gadget: f_ecm: Add get_status callback commit 8e3820271c517ceb89ab7442656ba49fa23ee1d0 upstream. When host sends GET_STATUS to ECM interface, handle the request from the function driver. Since the interface is wakeup capable, set the corresponding bit, and set RW bit if the function is already armed for wakeup by the host.
