Subject: [PATCH 2/2] backlight: arcxcnn_bl: drop of_match_ptr for ID table

The driver will match mostly by DT table (even thought there is regular
ID table) so there is little benefit in of_match_ptr (this also allows
ACPI matching via PRP0001, even though it might not be relevant here).

  drivers/video/backlight/arcxcnn_bl.c:378:34: error: ‘arcxcnn_dt_ids’ defined but not used [-Werror=unused-const-variable=]
