-	  This driver provides support for the LIS3LV02Dx accelerometer. In
-	  particular, it can be found in a number of HP laptops, which have the
-	  "Mobile Data Protection System 3D" or "3D DriveGuard" feature. On such
-	  systems the driver should load automatically (via ACPI). The
-	  accelerometer might also be found in other systems, connected via SPI
-	  or I2C.  The accelerometer data is readable via
-	  /sys/devices/platform/lis3lv02d.
-
-	  This driver also provides an absolute input class device, allowing
-	  the laptop to act as a pinball machine-esque joystick. On HP laptops,
-	  if the led infrastructure is activated, support for a led indicating
-	  disk protection will be provided as hp:red:hddprotection.
-
-	  This driver can also be built as modules.  If so, the core module
-	  will be called lis3lv02d and a specific module for HP laptops will be
-	  called hp_accel.

I haven't looked at all the patches, but I see may patches that are
changing only 1 or 2 lines. Do these really need to separated as such?

If you collate patches functionally, having description would also help.

Also, I noticed many changes to the defconfigs. You may want to take
a look at this discussion:

You really need to sanitize your patch series before posting and not
simply dump your internal tree with all its history.

[sp] I see 3 patches that are successively changing the same version number.

- Change log?
- run through checkpatch.pl
- Get rid of debug printks (or convert to dev_dbg)?
- use dev_XXX instrad of pr_xxx when you have device? Get rig
- I have seen lots of time people trying to call input_free_device
  after calling input_unregister_device (which is forbidden,
  input_unregister_device is sufficient alone) but you are the first to
  call free _before_ unregister.
- No need to initialize keymap with zeroes (NOKEYS)
- threaded IRQ
- copy keymap into device and set keycode, keycodemax, keycodesize so
  that keymap can be adjusted from userspace
- why do you export input device?

I dont think you tried applying this patch... At least I do not have
qci_kbd.c in my tree so it would not apply.

You may want to see the return val of the write? Else the return 0 may be misleading.

Free and then unregister ? Is it safe?

I think whole series needs a refresh as you had mentioned in the another email. No
point in reviewing this series, because Wayne needs to post only driver part here,
if he has some mach-msm bits, then they should go through Daniel Walker.
