From: Takashi Iwai Date: Thu, 8 Jan 2015 11:48:05 +0000 (+0100) Subject: ALSA: ice1724: Simplify PM callbacks X-Git-Tag: v4.14-rc1~5985^2~61^2~13 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=88942503538c7ef9636858851abbe50a96db3800;p=platform%2Fkernel%2Flinux-rpi.git ALSA: ice1724: 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.
