The driver will not quite work if someone unbinds the platform device from the platform driver via sysfs (moreover it will bomb is the driver built into the kernel as hp_wmi_bios_remove is marked as __exit and will not be present in the kernel). To fix it let's use platform_driver_probe() instead of platform_driver_register(), which disables binding/unbinding via sysfs. This also allows us to mark hp_wmi_bios_setup as __init and discard it once module is initialized. Signed-off-by:

We need to decrement "i" first because the current "i" was not allocated succesfully. Also we should go free the way down to zero to avoid a leak. Signed-off-by:

The call to handlers 0x124 and 0x135 (rfkill control) seems to take a bitmask to control various states of the device. For our rfkill we need a fully on/off. SVZ1311Z9R/X's LTE modem needs more bits up. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=47751Signed-off-by:

The new B series BIOS has version string 43CN46WW. The driver requires that 2nd and 3rd characters be 'E' and 'T' respectively, where as the newer BIOS has 'C' and 'N' respectively.

Found another Lenovo ideapad S205 the product name is 1038DPG, it has a 0x78 EC register exposes the state of wifi hardware switch on the machine. So, add this patch to support Lenovo ideapad S205-1038DPG wifi hardware switch in acer-wmi driver. Evidently the Ideapad S205 is just a model name on the market, but they have totally different product name in DMI table.

For machines with AMD graphic chips, it will send out WMI event and ACPI interrupt at the same time while hitting the hotkey. BIOS will notify the system the next display output mode throught WMI event code, so that windows' application can show an OSD to tell the user which mode will be taken effect. User can hit the display toggle key many times within 2 seconds to choose the mode they want. After 2 seconds, WMI dirver should send a WMIMethod(SDSP) command to tell the BIOS which mode the user chose. And then BIOS will raise another ACPI interrupt to tell the system to really switch the display mode. In Linux desktop, we don't have this kind of OSD to let users to choose the mode they want, so we don't need to call WMIMethod(SDSP) to have another ACPI interrupt. To simplify the problem, we just have to ignore the WMI event, and let the first ACPI interrupt to send out the key event. For the need, here comes another quirk to add machines with this kind of behavior. When the WMI driver receives the display toggle WMI event, and found the machin is in the list, it will do nothing and let ACPI video driver to report the key event. Signed-off-by:
