From e4e5f9e3bff79951cef7fd6912049b1cecf8a72d Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sun, 10 Dec 2023 18:43:56 +0100 Subject: usb: chipidea: Remove usage of the deprecated ida_simple_xx() API ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). This is less verbose.

This patch adds a check to bypass further usb events before controller resume finished to fix it.
