Subject: [PATCH 0/8] usb: gadget: dummy_hcd: coding style improvements and error handling change

This patch series focuses on addressing various coding style issues in
the dummy_hcd USB gadget driver. The changes include simplifying error
handling by preventing kernel-space crashes, improving readability, and
ensuring consistency with kernel coding conventions.

Clint George (8):
  usb: gadget: dummy_hcd: replace BUG() with WARN_ON_ONCE()
  usb: gadget: dummy_hcd: replace symbolic permissions (S_IRUGO) with
    octal (0444)
  usb: gadget: dummy_hcd: use 'unsigned int' instead of bare 'unsigned'
  usb: gadget: dummy_hcd: fix block comments, blank lines and function
    braces
  usb: gadget: dummy_hcd: merge multi-line quoted strings into one line
  usb: gadget: dummy_hcd: use sizeof(*ptr) instead of sizeof *ptr
  usb: gadget: dummy_hcd: remove unnecessary 'else' after return
  usb: gadget: dummy_hcd: fix miscellaneous coding style warnings

Testing:
-  Verified dummy_hcd module loading and behavior by checking dmesg logs
for expected output.
- Ran compiler testing with no new warnings detected.
- Ensured the module builds and inserts cleanly without issues.
- Used Static Analysis tools to confirm no new issues were introduced.

Please review the changes and let me know if any modifications
or further testing of the module is required. 

Thanks,
Clint
