PM: introduce set_target method in pm_ops

2007-07-01T19:29:44Z

Commit 52ade9b3b97fd3bea42842a056fe0786c28d0555 changed the suspend code ordering to execute pm_ops->prepare() after the device model per-device .suspend() calls in order to fix some ACPI-related issues. Unfortunately, it broke the at91 platform which assumed that pm_ops->prepare() would be called before suspending devices. at91 used pm_ops->prepare() to get notified of the target system sleep state, so that it could use this information while suspending devices. However, with the current suspend code ordering pm_ops->prepare() is called too late for this purpose. Thus, at91 needs an additional method in 'struct pm_ops' that will be used for notifying the platform of the target system sleep state. Moreover, in the future such a method will also be needed by ACPI. This patch adds the .set_target() method to 'struct pm_ops' and makes the suspend code call it, if implemented, before executing the device model per-device .suspend() calls. It also modifies the at91 code to use pm_ops->set_target() instead of pm_ops->prepare(). Signed-off-by: Rafael J.

smsc-ircc2: bypass PNP detection until we get the quirks worked out

2007-07-01T19:29:44Z

Don't use PNP detection by default yet. We have some PNP and BIOS issues to work out first. Sample problem on a Toshiba Portege 4000: the SMCf010 device is handed off disabled. We assign I/O ports originally assigned to the SMCf010 to a PCMCIA device instead. We enable the SMCf010, configuring it to use disjoint ports, but _SRS doesn't work correctly, so the device doesn't work.

asus_acpi: fix oops on non-asus machines

2007-07-01T19:29:44Z

If asus_acpi_init doesn't find any device it knows about, it mistakenly returns a "success" error code even though it cleans up after itself. Later when trying to rmmod asus_acpi, the module_exit routine would try to clean up one more time and we would end up calling acpi_bus_unregister_driver(&asus_hotk_driver) twice. This patch addresses this first problem by returning -ENODEV when no appropriate device is found. Then there was also another bug with the code handling the return value of backlight_device_register. If this function ever failed, the driver would cleanup by calling the module_exit routine from module_init, but it would still return "success". So any attempt to rmmod this module would result in asus_acpi_exit being called twice but it's not ready to handle it (I haven't hit this bug, just found it by code inspection). This patch fixes that by inserting a return -ENODEV; at the end of this error handling path.
