usb: dwc2: platform: Swap mode init order
From 157045fd728964f9c864863f70f5cb0e6e0ee8d8 Mon Sep 17 00:00:00 2001
From: Stefan Wahren <[email protected]>
Date: Sat, 13 May 2017 23:23:53 +0000
Subject: [PATCH] usb: dwc2: platform: Swap mode init order
Before this change there could be gadget enumeration issues in
dual mode. These might be caused by runtime issues between the gadget
and the hcd init. So swap the order to avoid this.

Possible fix NULL pointer dereference during VC4 binding

Subject: [PATCH] drm: vc4: Fix race during binding
This fixes the race between vc4_overflow_mem_work and the init of the
job lock. Otherwise we could trigger a NULL pointer dereference
during binding.
