From 6f9eb021f776e7765a054090932cc9834d99c242 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 8 Jan 2015 12:50:18 +0100 Subject: ALSA: trident: Simplify PM callbacks This is a similar cleanup like the commit [3db084fd0af5: ALSA: fm801: PCI core handles power state for us]. Since pci_set_power_state(), pci_save_state() and pci_restore_state() are already done in the PCI core side, so we don't need to it doubly. Also, pci_enable_device(), pci_disable_device() and pci_set_master() calls in PM callbacks are superfluous nowadays, too, so get rid of them as well.
