Both patch_realtek.c and patch_conexant.c contain the fairy same code snippet for supporting Thinkpad ACPI LED controls. Split them into thinkpad_helper.c and include it from both places. Although this isn't the best approach from the code size POV, the probability for coexistence of both Realtek and Conexant codecs on a single machine is pretty low, thus it'll end up with less memory footprint than splitting to yet another module.
