[PATCH 0/6] usb: add missing pm_runtime_dont_use_autosuspend() calls

From: Joshua Crofts

Date: Tue Sep 15 2026 - 05:43:35 EST


Several drivers in the USB subsystem forget to call dont_use_autosuspend()
on teardown or error, causing potential resource leaks. This series adds
the missing calls.

The offending drivers were found using a semantic patch for Coccinelle
I'm working on [1].
