Subject: [PATCH 6.12.y 1/2] iio: light: Remove redundant pm_runtime_mark_last_busy() calls
Date: Thu, 19 Mar 2026 14:34:37 -0400 [thread overview]
Message-ID: <20260319183438.2928887-1-sashal@kernel.org> (raw)
In-Reply-To: <2026031706-gentile-unbalance-017b@gregkh>
From: Sakari Ailus <sakari.ailus@linux.intel.com>
[ Upstream commit e15f23dd5305d123b571aeee56415d9e90f06ca4 ]
pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(),
pm_runtime_autosuspend() and pm_request_autosuspend() now include a call
to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to
pm_runtime_mark_last_busy().
