2013-07-03drivers: avoid format string in dev_set_nameKees Cook
Calling dev_set_name with a single paramter causes it to be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents, including wrappers like device_create*() and bdi_register().

2013-02-27hp-wmi: fix handling of platform deviceDmitry Torokhov
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.

2013-02-24thinkpad-acpi: enable loading module with new B-series Lenovo BIOSManoj Iyer
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. Failing to load the module causes some of the hotkeys to not work.

2013-02-24acer-wmi: support Lenovo ideapad S205 1038DPG wifi switchLee, Chun-Yi
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.
