From 9f9cd7ee2c05881f151e5ee4889e667a031dd8d9 Mon Sep 17 00:00:00 2001 From: Aaron Lu Date: Sat, 21 May 2016 15:30:46 +0800 Subject: ACPI / Thermal / video: fix max_level incorrect value commit 059500940def (ACPI/video: export acpi_video_get_levels) mistakenly dropped the correct value of max_level and that caused the set_level function following failed and the acpi_video backlight interface didn't get created. Fix this by passing back the correct max_level value. While at it, also fix the param used in acpi_video_device_lcd_query_levels where acpi_handle is expected but acpi_video_device is passed.
