Subject: [PATCH 0/6] usb: add missing pm_runtime_dont_use_autosuspend() calls
Date: Tue, 15 Sep 2026 09:02:17 +0000 [thread overview]
Message-ID: <20260915090223.1346-1-joshua.crofts1@gmail.com> (raw)
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].
