Subject: thinkpad-acpi: module autoloading for newer Lenovo ThinkPads.
X-Git-Tag: v2.6.32.47~15
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=2bc360b3483676fd47f7cd377d9464707bd80902;p=linux-pvops.git

thinkpad-acpi: module autoloading for newer Lenovo ThinkPads.

commit 9fbdaeb4f4dd14a0caa9fc35c496d5440c251a3a upstream.

The newer Lenovo ThinkPads have HKEY HID of LEN0068 instead
of IBM0068. Added new HID so that thinkpad_acpi module will
auto load on these newer Lenovo ThinkPads.
