Subject[PATCH 3.2 27/92] thinkpad-acpi: fix issuing duplicated key events for brightness up/down
3.2.60-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Hung <alex.hung@canonical.com>

commit ff413195e830541afeae469fc866ecd0319abd7e upstream.

The tp_features.bright_acpimode will not be set correctly for brightness
control because ACPI_VIDEO_HID will not be located in ACPI. As a result,
a duplicated key event will always be sent. acpi_video_backlight_support()
is sufficient to detect standard ACPI brightness control.
