ASoC: fix oops w/ for_each_rtd_codec_dai_rollback() macro

2018-10-30T15:31:11+00:00

A kernel oops happens on an error case (usual missing BE mixer
configuration required by Intel SST driver). Git bisect points to this
macro and an operator precedence issue.

	for (; ((i--) >= 0) && ((dai) = rtd->codec_dais[i]);)

The initial code replaced by this macro was
	while (--i >= 0) {
		codec_dai = rtd->codec_dais[i];

Fix the C operator precedence difference by reverting to pre-decrement

ASoC: core: add support to card rebind

2018-09-12T10:09:04+00:00

Current behaviour of ASoC core w.r.t to component removal is that it
unregisters dependent sound card totally. There is no support to
rebind the card if the component comes back.
Typical use case is DSP restart or kernel modules itself.

With this patch, core now maintains list of cards that are unbind due to
any of its depended components are removed and card not unregistered yet.
This list is cleared when the card is rebind successfully or when the
card is unregistered from machine driver.

This list of unbind cards are tried to bind once again after every new
component is successfully added, giving a fair chance for card bind
to be successful.
