Fixing the mute button on SL410

Right now the mute button on the SL410 doesn't work properly. In order for the sound to be muted you need to
press the mute button followed by one of the volume buttons (see
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/994274). But changing the keymap as
follows fixes the issue.

 <at>  <at>  -3157,7 +3157,7  <at>  <at>  static int __init hotkey_init(struct ibm_init_struct *iibm)
                 */
                KEY_RESERVED,   /* 0x14: VOLUME UP */
                KEY_RESERVED,   /* 0x15: VOLUME DOWN */
-               KEY_RESERVED,   /* 0x16: MUTE */
+               KEY_MUTE,       /* 0x16: MUTE */

                KEY_VENDOR,     /* 0x17: Thinkpad/AccessIBM/Lenovo */

The LED still doesn't work, but hey, at least mute works. The comments above it says that the "firmware may
react very differently" if the keymap is changed. So is it okay to change the keymap? Would there be any side effects?

ACPI problem with Lenovo x230

Hi.

I found that my brightness control does not work very well on linux.
One time I found this message in my logs so I'm just writting.

Should I fill bug report?
If you are interested I can test new versions of the module and do more tests.

All best,
Tomasz Czyż

What information would you like?  I have the Lenovo Twist, just upgraded 
to Ubuntu 14.04.  I ran 12.04 on it for a year, ACPI was always a 
problem.  It works as long as I never let it enter sleep mode on 
battery, or operate on batter for too long.  So I always plug in and it 
always works reliably.

I would be willing to send more information, just let me know what you need.

unsupported brightness interface

I am getting the following message during bootup (kern.log):

Apr 17 22:23:02 euler kernel: [    9.036321] thinkpad_acpi: ThinkPad BIOS GJET64WW (2.14 ), EC unknown
Apr 17 22:23:02 euler kernel: [    9.036323] thinkpad_acpi: Lenovo ThinkPad T440s, model 20AQCTO1WW

This is on a Thinkpad 440s running debian/jessie with an experimental kernel.

The message says to contact the list, well, here it is, let me know what other info I can provide.

The brightness control indeed does not work on this laptop. The buttons F5/F6 are not working properly. xbacklight does work.

Thanks for your attention,
-Matyas
