From: Hans de Goede Date: Tue, 17 Dec 2013 15:24:57 +0000 (+0100) Subject: regulator: core: don't print an error when no regulator is found X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0781719bd6614e60dd5fff1b5cd45dbce2f7dd2d;p=linux-beck.git regulator: core: don't print an error when no regulator is found Only print an error when _regulator_get() is expected to return a valid regulator, that is when _regulator_get() is called from regulator_get() and we're not using the dummy because we don't have full-constraints, or when _regulator_get() is called from regulator_get_exclusive() in which case returning a dummy is not allowed.
