2011-03-31classmate-laptop: depends on RFKILL or RFKILL=nThadeu Lima de Souza Cascardo
[ upstream commit f35843ed8d17562f7c5da4b34a4a81b0cc450e9e ] Randy Dunlap has reported that building classmate-laptop fails when CONFIG_RFKILL=m and CONFIG_ACPI_CMPC=y. He suggested depending on RFKILL, but, then, it will not be possible to select classmate-laptop when RFKILL is off. There's no known problem with building and using classmate-laptop with RFKILL off. So depend on RFKILL or RFKILL=n.

2010-12-14wmi: use memcmp instead of strncmp to compare GUIDsThadeu Lima de Souza Cascardo
commit 8b14d7b22c61f17ccb869e0047d9df6dd9f50a9f upstream. While looking for the duplicates in /sys/class/wmi/, I couldn't find them. The code that looks for duplicates uses strncmp in a binary GUID, which may contain zero bytes. The right function is memcmp, which is also used in another section of wmi code. It was finding 49142400-C6A3-40FA-BADB-8A2652834100 as a duplicate of 39142400-C6A3-40FA-BADB-8A2652834100. Since the first byte is the fourth printed, they were found as equal by strncmp.

2010-05-16thinkpad-acpi: fix volume/mute hotkey poll handlingHenrique de Moraes Holschuh
The hotkey polling code is supposed to generate hotkey messages as close to the way the IBM event-based volume hotkey firmware does as possible, i.e: * Pressing MUTE issues a mute hotkey event, even if already mute; * Pressing Volume up/down issues a volume up/down hotkey event, even if already at maximum or minumum volume; * The act of unmuting issues a volume up/down event, depending on which hotkey was used to unmute. Fix the code to do just that (mute handling was incorrect), and handle multiple hotkey presses between two polling cycles. The new code uses the volume_toggle bit in NVRAM only to detect repeated presses of the mute key and multiple presses of the volume keys trying to go past the end of the volume scale. This will work around a bug in recent Lenovo firmware (e.g. T400), which causes the firmware to not update the volume_toggle bit in certain situations.

Lenovo is playing around with its ACPI BIOS, and will end up reusing method names. Their memory is not nearly as long as thinkpad-acpi's... Secure most of the old IBM codepaths against running in a non-IBM box. This would happen on the Lenovo X100e in video_init(), for example. We would misdetect it as an ancient model 570 firmware. Also, refuse to load the driver if we cannot identify the vendor. No ACPI ThinkPad in existence lacks this information, AFAIK. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br>
