From 53052539f3e2b29ccaf2064b0d3b8cee51d05621 Mon Sep 17 00:00:00 2001 From: Patrick Mochel Date: Fri, 6 Jan 2006 00:15:18 -0800 Subject: [PATCH] [PATCH] oss: remove deprecated PM interface from maestro driver This change removes the old, deprecated interface from the maestro driver, including the pm_{,un}register() calls, the local storage of the pmdev object and the reference to the old header files. This change is done to assist in eradicating the users of the legacy interface so as to help facilitate the removal of the interface itself. The check_suspend() function and associated logic was not removed, even though it is now unnecessary. Note that this driver has been obsoleted by an ALSA equivalent.
