From f892a21f51162d2c443c972d450f73ffa7fb49bb Mon Sep 17 00:00:00 2001 From: Vaibhav Gupta Date: Wed, 22 Jul 2020 15:00:58 +0530 Subject: crypto: ccp - use generic power management Drivers using legacy power management .suspen()/.resume() callbacks have to manage PCI states and device's PM states themselves. They also need to take care of standard configuration registers. Switch to generic power management framework using a single "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions as through the generic framework, PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.
