no they doesn't, but here is a part of pxa2xx-flash.c and driver
structure registered by driver_register call. Is it problem ?
static struct device_driver pxa2xx_flash_driver = {
.name = "pxa2xx-flash",
.bus = &platform_bus_type,
.probe = pxa2xx_flash_probe,
.remove = __exit_p(pxa2xx_flash_remove),
.suspend = pxa2xx_flash_suspend,
.resume = pxa2xx_flash_resume,
.shutdown = pxa2xx_flash_shutdown,
};
static int __init init_pxa2xx_flash(void)
{
return driver_register(&pxa2xx_flash_driver);
}
static void __exit cleanup_pxa2xx_flash(void)
{
driver_unregister(&pxa2xx_flash_driver);
}
On 2.6.24 kernel driver structure register the same way but sleep mode
works fine there.
