From 30b35399ceb2398d05837863476dcb12f12f3a82 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 11 Oct 2006 18:52:53 +0200 Subject: [ALSA] Various fixes for suspend/resume of ALSA PCI drivers - Check the return value of pci_enable_device() and request_irq() in the suspend. If any error occurs there, disable the device using snd_card_disconnect(). - Call pci_set_power_state() properly with pci_choose_state(). - Fix the order to call pci_set_power_state(). - Removed obsolete house-made PM codes in some drivers.
