+Subject: ACPI / video: Add "Asus UL30A" to ACPI video detect blacklist
+
+From: Bastian Triller <bastian.triller@gmail.com>
+
+commit c8f6d8351ba8c89d5cd4c562552ec7ec29274e31 upstream.
+
+Like on UL30VT, the ACPI video driver can't control backlight correctly on
+Asus UL30A. Vendor driver (asus-laptop) can work. This patch is to
+add "Asus UL30A" to ACPI video detect blacklist in order to use
+asus-laptop for video control on the "Asus UL30A" rather than ACPI
+video driver.

+Subject: ACPI video: ignore BIOS initial backlight value for HP 1000
+
+From: Alex Hung <alex.hung@canonical.com>
+
+commit 4ef366c583d6180b1c951147869ee5a3038834f2 upstream.
+
+On HP 1000 lapops, BIOS reports minimum backlight on boot and
+causes backlight to dim completely. This ignores the initial backlight
+values and set to max brightness.

+Subject: acpi/video_detect: blacklist samsung x360
+
+From: Corentin Chary <corentin.chary@gmail.com>
+
+commit 084940d5b101e9ca91a689eb5048151b14076839 upstream.
+
+On Samsung X360, the BIOS will set a flag (VDRV) if the generic
+ACPI backlight device is used. This flag will definitively break
+the backlight interface (even the vendor interface) untill next
+reboot. It's why we should prevent video.ko from being used here
+and we can't rely on a later call to acpi_video_unregister().

+Subject: staging: comedi: das08: Correct AI encoding for das08jr-16-ao
+
+From: Ian Abbott <abbotti@mev.co.uk>
+
+commit e6391a182865efc896cb2a8d79e07b7ac2f45b48 upstream.
+
+The element of `das08_boards[]` for the 'das08jr-16-ao' board has the
+`ai_encoding` member set to `das08_encode12`. It should be set to
+`das08_encode16` same as the 'das08jr/16' board. After all, this board
+has 16-bit AI resolution.
+
+The description of the A/D LSB register at offset 0 seems incorrect in
+the user manual "cio-das08jr-16-ao.pdf" as it implies that the AI
+resolution is only 12 bits. The diagrams of the A/D LSB and MSB
+registers show 15 data bits and a sign bit, which matches what the
+software expects for the `das08_encode16` AI encoding method.
