Subject: [PATCH v3 02/14] clk: cdce925: simplify using devm_regulator_get_enable()
Date: Fri, 19 Aug 2022 22:17:53 +0300	[thread overview]
Message-ID: <1f46b06be44527a93cd0bfd5de2fa8e2899524ab.1660934107.git.mazziesaccount@gmail.com> (raw)
In-Reply-To: <cover.1660934107.git.mazziesaccount@gmail.com>

[-- Attachment #1: Type: text/plain, Size: 1929 bytes --]

Simplify the driver using devm_regulator_get_enable() instead of
open-coding the devm_add_action_or_reset().

A (minor?) functional change is that we don't print an error in case of a
deferred probe. Now we also print the error no matter which of the
involved calls caused the failure.
