[PATCH 0/2] ASoC: fix hw_params/hw_free validity checks

[Jerome Brunet <jbrunet@baylibre.com>]

While working on a codec, I have found an odd situation. The hw_params
callback which was provided by the codec dai was not called as expected.
However, the hw_free callback was called, even if hw_params was skipped.

After debugging, I found out that the dai was considered invalid because
it did not specify any rates, only rate_min and rate_max. That's a first
problem.

If a codec dai is considered invalid, hw_free should probably not be
called either, that's a 2nd issue.

This patchset is meant to solve both issues.
