From 70090bbb8b7d7da7a6f64969b43a61c493c560ff Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Tue, 19 Aug 2014 15:51:24 +0200 Subject: [PATCH] ASoC: Move component->probed check into soc_{remove,probe}_component() 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.
