[alsa-devel] [PATCH 07/13] ASoC: Move component->probed check into soc_{remove, probe}_component()

Tue Aug 19 15:51:24 CEST 2014


Having the check in a centralized place makes the code a bit cleaner and
shorter.

Note: There is a slight semantic change in this patch. soc_probe_aux_dev() will
no longer return -EBUSY if the AUX dev has already been probed before. This is
fine though since it will simply do nothing in that case and return success.
