From 0966648dd5a5f4037d29d233866b7a4db39d07f7 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Tue, 25 Jun 2019 14:38:46 +0900 Subject: [PATCH] usb: renesas_usbhs: remove notify_hotplug callback The notify_hotplug callback was supported in v3.10, but the last user (armadillo800eva) was removed by the commit 1fa59bda21c7 ("ARM: shmobile: Remove legacy board code for Armadillo-800 EVA"). So, this patch removes it.
