stable inclusion from stable-5.10.50 commit 63d6029e6608588d9fe42adcbcacc42c87297d6e bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
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.
