[PATCH] iio: accel: mma8452: use pm_ptr() for dev_pm_ops

[Sanjay Chitroda <sanjayembeddedse@gmail.com>]

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.
