devm_kasprintf() can fail while building the temporary speaker
component string. If that happens, spk_components is set to NULL, but
the current code can still pass it to strlen() on a later loop iteration
or after the loop when appending the speaker component list to
card->components.
Use NULL to represent the initial "no speaker components" state, and
return -ENOMEM immediately if building spk_components fails.
