Subject: [PATCH v3 07/27] Input: bu21013_ts - Simplify with dev_err_probe()
Date: Thu, 27 Aug 2020 20:58:09 +0200	[thread overview]
Message-ID: <20200827185829.30096-8-krzk@kernel.org> (raw)
In-Reply-To: <20200827185829.30096-1-krzk@kernel.org>

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

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
Reviewed-by: Hans de Goede <hdegoede@redhat.com>

Changes since v1:
1. Remove unneeded PTR_ERR_OR_ZERO, as pointed by Andy.
