	help
	 Say Y or M if you want to add support for I2S driver for
	 Synopsys desigwnware I2S device. The device supports upto
	 maximum of 8 channels each for play and record.

config SND_DESIGNWARE_PCM
	tristate "PCM PIO extension for I2S driver"
	depends on SND_DESIGNWARE_I2S
	help
	 Say Y, M or N if you want to add a custom ALSA extension that registers
	 a PCM and uses PIO to transfer data.

	 This functionality is specially suited for I2S devices that don't have
	 DMA support.

PCI/MSI: Don't apply affinity if there aren't enough vectors left
Bart reported a problem wіth an out of bounds access in the low-level IRQ affinity code, which we root caused to the qla2xxx driver assigning all its MSI-X vectors to the pre and post vectors, and not having any left for the actually spread IRQs. Fix this issue by not asking for affinity assignment when there are no vectors to assign left.
