From 26ec685ff9d9c16525d8ec4c97e52fcdb187b302 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 11 May 2012 07:51:17 +0200 Subject: vga_switcheroo: Introduce struct vga_switcheroo_client_ops This changes the API as a clean-up. Instead of passing multiple function pointers at each time, introduce a new struct holding the whole callback functions and pass it to the registration. The same struct will be used for the upcoming audio client registration, too.

The id of the audio controller should be given explicitly at registration time unlike the video controller.
