Subject: thinkpad-acpi: module autoloading for newer Lenovo ThinkPads.
X-Git-Tag: firefly_0821_release~7613^2~1484^2~3
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9fbdaeb4f4dd14a0caa9fc35c496d5440c251a3a;p=firefly-linux-kernel-4.4.55.git

thinkpad-acpi: module autoloading for newer Lenovo ThinkPads.

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.
