Subject: [PATCH 1/6] pwm: bcm2835: Simplify with dev_err_probe()
Date:   Wed, 26 Aug 2020 16:47:42 +0200
Message-Id: <20200826144747.9436-1-krzk@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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