Pull sound fixes from Takashi Iwai: "The only significant change is for OSS PCM emulation to convert with kvcalloc() to address both performance and security issues. It's a pretty straightforward change, which should be safe. The rest are, as usual, device-specific small fixes for HD-audio" * tag 'sound-4.20-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ALSA: hda/ca0132 - fix AE-5 pincfg ALSA: hda/ca0132 - Add new ZxR quirk ALSA: hda/ca0132 - Call pci_iounmap() instead of iounmap() ALSA: hda/realtek - Add quirk entry for HP Pavilion 15 ALSA: oss: Use kvzalloc() for local buffer allocations
