Subject: [PATCH v4 11/13] ASoC: arizona-jack: Cleanup logging
Date:   Sat, 23 Jan 2021 13:17:18 +0100
Message-Id: <20210123121720.79863-2-hdegoede@redhat.com>
In-Reply-To: <20210123121720.79863-1-hdegoede@redhat.com>

 <20210123121720.79863-1-hdegoede@redhat.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Cleanup the use of dev_foo functions used for logging:

1. Many of these are unnecessarily split over multiple lines
2. Use dev_err_probe() in cases where we might get a -EPROBE_DEFER
   return value

Suggested-by: Andy Shevchenko <andy.shevchenko@gmail.com>

Changes in v4:
- While at it also change (on adjescent lines) "if (ret != 0)" into "if (ret)"
- Do not unnecessary split one of the dev_err_probe() calls over multiple lines

Changes in v3:
- This is a new patch in v3 of this patch-series
