[PATCH 5.12 024/700] usb: dwc3: Fix debugfs creation flow
From: Greg Kroah-Hartman
Date: Mon Jul 12 2021 - 03:19:58 EST
From: Minas Harutyunyan <Minas.Harutyunyan@xxxxxxxxxxxx>
commit 84524d1232ecca7cf8678e851b254f05cff4040a upstream.
Creation EP's debugfs called earlier than debugfs folder for dwc3
device created. As result EP's debugfs are created in '/sys/kernel/debug'
instead of '/sys/kernel/debug/usb/dwc3.1.auto'.
Moved dwc3_debugfs_init() function call before calling
dwc3_core_init_mode() to allow create dwc3 debugfs parent before
creating EP's debugfs's.
Fixes: 8d396bb0a5b6 ("usb: dwc3: debugfs: Add and remove endpoint dirs dynamically")
