[PATCH] rpmsg: core: Drop dev_pm_domain_detach() call
From: Claudiu
Date: Wed Aug 27 2025 - 06:14:07 EST
From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>
Starting with commit f99508074e78 ("PM: domains: Detach on
device_unbind_cleanup()"), there is no longer a need to call
dev_pm_domain_detach() in the bus remove function. The
device_unbind_cleanup() function now handles this to avoid
invoking devres cleanup handlers while the PM domain is
powered off, which could otherwise lead to failures as
described in the above-mentioned commit.
Drop the explicit dev_pm_domain_detach() call and rely instead
on the flags passed to dev_pm_domain_attach() to power off the
domain.
