From 391d8a04fc0f0d603642daa07f379e17c88001c9 Mon Sep 17 00:00:00 2001 From: Dimitris Papastamos Date: Tue, 21 Sep 2010 17:04:07 +0100 Subject: [PATCH] ASoC: Return -1 instead of -EINVAL to ensure consistency The code can't really cope with I/O errors, so it would be better to be consistent throughout all cache functions and return -1 instead of -EINVAL. The return value of snd_soc_read(...) is mostly checked in the probe function and nowhere else.
