[PATCH v3 0/2] Add a new debugfs entry to dump FIFO/Queue available space

[changbin . du]

From: "Du, Changbin" <changbin.du@xxxxxxxxx>

FIFO/Queue available space info can be used to debug dwc3 issues.
First we remove unnecessary checking for debugfs api call, then add
the new entry.

changes from v2:
   1. Remove commit "usb: dwc3: free dwc->regset on dwc3_debugfs_exit"

Du, Changbin (2):
  usb: dwc3: make dwc3_debugfs_init return value be void
  usb: dwc3: add debugfs node to dump FIFO/Queue available space
