[PATCH 0/4] asus-laptop: Pegatron Lucid (WeTab/ExoPC) support

[Andy Ross <andy.ross@windriver.com>]

Accelerometer and ambient light sensor drivers for the Pegatron Lucid
(sold as WeTab and ExoPC) tablet PC.

This was submitted a while back, but got dropped before merge as we
were distracted by other projects.  The last change requested was to
fold the accelerometer driver into asus-laptop, which has been done
here.

Unfortunately there is one new wart: doing so causes initialization to
occur earlier, and we were seeing common panics underneath ACPI
initialization.  So I moved the accelerometer initialization out of
the ACPI startup call tree and into a separate platform driver (as it
was earlier when it was a separate module), which helped some.  But
occasional panics persisted, which I eventually tracked down to the
very first accelerometer reads.

Faking this initial report (which I *think* is being requested out of
the input polldev layer, not userspace) resulted in stable behavior.
This code has been running on a bunch of development systems for
several months now, so I feel as comfortable with the voodoo as I
think I can.
