Subject: [PATCH] iio: accel: mma8452: use pm_ptr() for dev_pm_ops
Date: Wed, 15 Apr 2026 00:50:45 +0530 [thread overview]
Message-ID: <20260414192045.3598010-1-sanjayembedded@gmail.com> (raw)
From: Sanjay Chitroda <sanjayembeddedse@gmail.com>
Use pm_ptr() so the PM ops pointer is automatically set to
NULL when CONFIG_PM is disabled. This avoids unused-function warnings
and follows modern kernel power-management conventions.
