thinkpad-acpi: disable broken bay and dock subdrivers

2009-08-16T21:26:44+00:00

commit 550e7fd8afb7664ae7cedb398c407694e2bf7d3c upstream.

Currently, the ThinkPad-ACPI bay and dock drivers are completely
broken, and cause a NULL pointer derreference in kernel mode (and,
therefore, an OOPS) when they try to issue events (i.e. on dock,
undock, bay ejection, etc).

OTOH, the standard ACPI dock driver can handle the hotplug bays and
docks of the ThinkPads just fine (including batteries) as of 2.6.27.
In fact, it does a much better job of it than thinkpad-acpi ever did.

It is just not worth the hassle to find a way to fix this crap without
breaking the (deprecated) thinkpad-acpi dock/bay ABI.  This is old,
deprecated code that sees little testing or use.

As a quick fix suitable for -stable backports, mark the thinkpad-acpi
bay and dock subdrivers as BROKEN in Kconfig.  The dead code will be
removed by a later patch.

This fixes bugzilla #13669, and should be applied to 2.6.27 and later.

thinkpad-acpi: fix LED blinking through timer trigger

2009-05-02T17:25:04+00:00

commit 75bd3bf2ade9d548be0d2bde60b5ee0fdce0b127 upstream.

The set_blink hook code in the LED subdriver would never manage to get
a LED to blink, and instead it would just turn it on.  The consequence
of this is that the "timer" trigger would not cause the LED to blink
if given default parameters.

This problem exists since 2.6.26-rc1.

To fix it, switch the deferred LED work handling to use the
thinkpad-acpi-specific LED status (off/on/blink) directly.

This also makes the code easier to read, and to extend later.

thinkpad-acpi: fix module autoloading for older models

2009-03-23T22:00:02+00:00

commit b36a50f92d1c4300a88f606b4d2bbdc4f442a2d7 upstream.

Looking at the source, there seems to be a missing * to match my DMI
string.  I mean for newer IBM and Lenovo's laptops you match either one
of the following:
MODULE_ALIAS("dmi:bvnIBM:*:svnIBM:*:pvrThinkPad*:rvnIBM:*");
MODULE_ALIAS("dmi:bvnLENOVO:*:svnLENOVO:*:pvrThinkPad*:rvnLENOVO:*");

While for older Thinkpads, you do this (for instance):
IBM_BIOS_MODULE_ALIAS("1[0,3,6,8,A-G,I,K,M-P,S,T]");

with IBM_BIOS_MODULE_ALIAS being MODULE_ALIAS("dmi:bvnIBM:bvr" __type "ET??WW")

Note there's no * terminating the string.  As result, udev doesn't load
anything because modprobe cannot find anything matching this (my
machine actually):

udevtest: run: '/sbin/modprobe dmi:bvnIBM:bvr1IET71WW(2.10):bd06/16/2006:svnIBM:pn236621U:pvrNotAv

sgi-xp: fix writing past the end of kzalloc()'d space

2009-02-12T17:31:03+00:00

commit 361916a943cd9dbda1c0b00879d0225cc919d868 upstream.

A missing type cast results in writing way beyond the end of a kzalloc()'d
memory segment resulting in slab corruption. But it seems like the better
solution is to define ->recv_msg_slots as a 'void *' rather than a
'struct xpc_notify_mq_msg_uv *' and add the type cast.

eeepc-laptop: fix oops when changing backlight brightness during eeepc-laptop init

2009-02-12T17:31:01+00:00

commit 7695fb04aca62e2d8a7ca6ede50f6211e1d71e53 upstream.

I got the following oops while changing the backlight brightness during
startup.  When it happens, it prevents use of the hotkeys, Fn-Fx, and the
lid button.

It's a clear use-before-init, as I verified by testing with an
appropriately-placed "else printk".
