--- NEW FILE linux-2.6-acpi-git-ec-init-fixes.patch ---
From: Alexey Starikovskiy <astarikovskiy at suse.de>

Subject: ACPI: EC: Drop ECDT-based boot_ec as soon as we find DSDT-based one.
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Flenb%2Flinux-acpi-2.6.git;a=commitdiff_plain;h=4c611060660f0de3e9b8f02df207312bc6f5c331
ACPI: EC: Drop ECDT-based boot_ec as soon as we find DSDT-based one.
ASUS notebooks have numerous problems with EC initialization
This patch tries to work around three known issues reported
in bugzilla 8598, 8709 and 8909/8919.
