Subject: [PATCH v1 03/11] starfire: use generic power management
Date: Wed,  1 Jul 2020 18:29:30 +0530
Message-ID: <20200701125938.639447-4-vaibhavgupta40@gmail.com> (raw)
In-Reply-To: <20200701125938.639447-1-vaibhavgupta40@gmail.com>

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states.

After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.

Thus, there is no need to call the PCI helper functions like
pci_save/restore_sate() and pci_set_power_state().

Compile-tested only.
