[PATCH 0/4] usb: enable sysfs module symlink for more built-in drivers

From: Shashank Balaji <hidden>
Date: 2026-07-22 03:41:47
Also in: linux-usb, lkml

This is in continuation to [1].

struct device_driver's mod_name is not set by a number of bus' driver registration
functions. Without that, built-in drivers don't have the module symlink in sysfs.
We want this to go from unbound driver name -> module name -> kernel config name.
This is useful on embedded platforms to minimize kernel config, reduce kernel size,
and reduce boot time.

This patchset adds mod_name to usb-related drivers.
