Subject: [PATCH 1/5] PM: runtime: Only queue an idle check for RPM-linked suppliers (part 2)
Date: Fri, 2 Oct 2026 16:03:05 -0700 [thread overview]
Message-ID: <20261002160309.1.If69ddc515c2e9fd4338441e87688b9d690d2ef36@changeid> (raw)
In-Reply-To: <20261002230714.507921-1-briannorris@chromium.org>
Commit be5755f023e7 ("PM: runtime: Only queue an idle check for
RPM-linked suppliers") was incomplete. There are two other cases where
we perform idle checks on non-DL_FLAG_PM_RUNTIME suppliers -- in
pm_runtime_set_suspended(), and in cases were we failed to resume
suppliers.
Fixes: 5244f5e2d801 ("PM: runtime: Defer suspending suppliers")
