stable inclusion from stable-v6.6.2 commit 82236047df77172009176661be0d9c527505b8fe category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 2d5661e6008ae1a1cd6df7cc844908fb8b982c58 ]
According to the documentation, drivers are responsible for undoing at removal time all runtime PM changes done during probing.
Hence, add the missing calls to pm_runtime_dont_use_autosuspend(), which are necessary for undoing pm_runtime_use_autosuspend().
Note this would have been handled implicitly by devm_pm_runtime_enable(), but there is a need to continue using pm_runtime_enable()/pm_runtime_disable() in order to ensure the runtime PM is disabled as soon as the remove() callback is entered.
