Subject: [PATCH v1 2/3] hwmon: tmp513: Simplify with dev_err_probe()
Date: Tue, 28 Nov 2023 20:06:03 +0200	[thread overview]
Message-ID: <20231128180654.395692-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20231128180654.395692-1-andriy.shevchenko@linux.intel.com>

Common pattern of handling deferred probe can be simplified with
dev_err_probe().  Less code and also it prints the error value.
