[PATCH 00/10] [Intrepid] SRU: LP#257827 -- acpi brightness control

[Andy Whitcroft]

This series represents a backport of a change to the ACPI backlight
support.  This change was original done to sort out brightness control
problems for a number of different laptop models triggered by non-existant
devices being created (as reported on this bug).  These changes also
are reported to fix boot crashes on a number of Samsung laptops (as
reported on LP#146692).  All of these changes are direct back ports from
mainline, no changes were needed to apply them.  They are all upstream
as of v2.6.28-rc5.

I have built test kernels with these applied and a number of community
members have tested these and confirm that they do indeed allow those
laptops to boot and brightness control is improved there.

Proposing these for SRU to Intrepid.
