The previous cleanup with devres may lead to the incorrect release orders at the probe error handling due to the devres's nature. Until we register the card, snd_card_free() has to be called at first for releasing the stuff properly when the driver tries to manage and release the stuff via card->private_free(). This patch fixes it by calling snd_card_free() on the error from the probe callback using a new helper function.

The previous cleanup with devres forgot to replace the snd_card_free() call with the devm version. Moreover, it still needs the manual call of snd_card_free() at the probe error path, otherwise the reverse order of the releases may happen. This patch addresses those issues.

This is a small helper function to handle the error path more easily when an error happens during the probe for the device with the device-managed card. Since devres releases in the reverser order of the creations, usually snd_card_free() gets called at the last in the probe error path unless it already reached snd_card_register() calls. Due to this nature, when a driver expects the resource releases in card->private_free, this might be called too lately. As a workaround, one should call the probe like: static int __some_probe(...) { // do real probe.... } static int some_probe(...) { return snd_card_free_on_error(dev, __some_probe(dev, ...)); } so that the snd_card_free() is called explicitly at the beginning of the error path from the probe. This function will be used in the upcoming fixes to address the regressions by devres usages.

For this specific device on Lenovo Thinkpad X12 tablet, the verbs were dumped by qemu running a guest OS that init this codec properly. After studying the dump, it turns out that the same quirk used by the other Lenovo devices can be reused. The patch was tested working against the mainline kernel.

The current limit of max buffer size 1MB seems too small for modern devices with lots of channels and high sample rates. Let's make bigger, 4MB.

In the implicit feedback mode, some parameters are tied between both playback and capture streams. One of the tied parameters is the period size, and this can be a problem if the device has different number of channels to both streams. Assume that an application opens a playback stream that has an implicit feedback from a capture stream, and it allocates up to the max period and buffer size as much as possible. When the capture device supports only more channels than the playback, the minimum period and buffer sizes become larger than the sizes the playback stream took. That is, the minimum size will be over the max size the driver limits, and PCM core sees as if no available configuration is found, returning -EINVAL mercilessly. For avoiding this problem, we have to look through the counter part of audioformat list for each sync ep, and checks the channels. If more channels are found there, we reduce the max period and buffer sizes accordingly. You may wonder that the patch adds only the evaluation of channels between streams, and what about other parameters? Both the format and the rate are tied in the implicit fb mode, hence they are always identical.
