| |
From: Rafael J. Wysocki <rjw@sisk.pl>
Make the tpm_atmel driver define its PM callbacks through a struct dev_pm_ops object rather than by using legacy PM hooks in struct platform_driver.
This allows the driver to use tpm_pm_suspend() and tpm_pm_resume() as its PM callbacks directly, without defining its own PM callback routines.
