2008-09-13ia64: fix panic during `modprobe -r xpc'Robin Holt1-0/+3
If you are on ia64 and you modprobe xpc then modprobe -r xpc, you immediately get a panic. xpc depends on xp which depends on gru for a symbol. That symbol is only used when we are running on UV hardware. Currently, the GRU driver detects we are not on UV hardware and does no initializing. It does not do the same check when unloading. As a result, the gru driver attempts to tear down stuff that was not setup. This is a simple two-line workaround to get us through this release. Once 2.6.28 is opened, we need to rework the symbols that xp is depending on from gru so the gru driver can properly fail to load when hardware is not available.

2008-09-04fujitsu-laptop: fix regression for P8010 in 2.6.27-rcJonathan Woithe1-0/+7
The following patch (based on a patch from Stephen Gildea) fixes a regression with the LCD brightness keys on Fujitsu P8010 laptops which was observed with the 2.6.27-rc series (basically they stopped working due to changes within the fujitsu-laptop and video modules). Please apply to 2.6.27-rc and acpi git. A more complete solution for this laptop will be included in an upcoming patch, hopefully for 2.6.28. In the meantime this restores most functionality for P8010 users.

2008-09-02hp-wmi: update to match current rfkill semanticsMatthew Garrett1-35/+46
hp-wmi currently changes the RFKill state by altering the struct members rather than using the dedicated interface, meaning that update events won't be pushed to userspace. This patch fixes that, along with fixing the declared type of the WWAN kill switch. It also ensures that rfkill interfaces are only registered for hardware that exists.

2008-08-23Fix oops in acer_wmi driver (acer_wmi_init)Arjan van de Ven1-0/+5
The acer_wmi driver does a DMI scan for quirks, and then sets flags into the "interface" datastructure for some cases. However, the quirks happen real early before "interface" is per se initialized from NULL. The patch below 1) adds a NULL pointer check and 2) (re)runs the quirks at the end, when "interface" has it's final value.

2008-08-15acer-wmi: Fix wireless and bluetooth on early AMW0 v2 laptopsCarlos Corbacho1-0/+19
In the old acer_acpi, I discovered that on some of the newer AMW0 laptops that supported the WMID methods, they don't work properly for setting the wireless and bluetooth values. So for the AMW0 V2 laptops, we want to use both the 'old' AMW0 and the 'new' WMID methods for setting wireless & bluetooth to guarantee we always enable it. This was fixed in acer_acpi some time ago, but I forgot to port the patch over to acer-wmi when it was merged. (Without this patch, early AMW0 V2 laptops such as the Aspire 5040 won't work with acer-wmi, where-as they did with the old acer_acpi).
