[PATCH v6] ata: ahci_da850: switch to DEFINE_SIMPLE_DEV_PM_OPS

[PATCH v6] ata: ahci_da850: switch to DEFINE_SIMPLE_DEV_PM_OPS

[Li Jun]

Replace the deprecated SIMPLE_DEV_PM_OPS macro with the recommended
DEFINE_SIMPLE_DEV_PM_OPS. Use pm_sleep_ptr(&ahci_da850_pm_ops) to complete
the API migration and allow the structure to be correctly dropped
when CONFIG_PM_SLEEP=n.

changelogs:
-add pm_ptr for ahci_da850_pm_ops in ahci_da850_driver.
-revise grammar and alignment issues.
-Align parentheses.
-change pm_ptr to pm_sleep_ptr.
-Modify pm_ptr\CONFIG_PM to pm_sleep_ptr\CONFIG_PM_SLEEP in commit
message.

I fixed up the commit message when applying your v5:
https://git.kernel.org/pub/scm/linux/kernel/git/libata/linux.git/commit/?id=f091e60fc986eb12ff632f682848b88da824bccb

So there was no need to send a v6 :)

Thank you for your contribution!


Kind regards,
Niklas
