2021-09-30	ALSA: virtio: Replace zero-length array with flexible-array member	Gustavo A. R. Silva	1	-3/+2
	There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Also, make use of the struct_size() helper in kzalloc().

2021-03-07	ALSA: virtio: handling control and I/O messages for the PCM device	Anton Yakovlev	1	-0/+414
	The driver implements a message-based transport for I/O substream operations. Before the start of the substream, the hardware buffer is sliced into I/O messages, the number of which is equal to the current number of periods. The size of each message is equal to the current size of one period. I/O messages are organized in an ordered queue. The completion of the I/O message indicates an elapsed period (the only exception is the end of the stream for the capture substream). Upon completion, the message is automatically re-added to the end of the queue.
