From: Takashi Iwai Date: Thu, 8 Jan 2015 11:44:01 +0000 (+0100) Subject: ALSA: als4000: Simplify PM callbacks X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dc3b10eb64edd977fb5173f72fc66cc8687e61be;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ALSA: als4000: 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.
