Subject: [PATCH 1/2] irqchip/ti-sci: Simplify with dev_err_probe()
Date: Wed,  2 Sep 2020 19:46:14 +0200	[thread overview]
Message-ID: <20200902174615.24695-1-krzk@kernel.org> (raw)

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

There is also no need to assign NULL to 'intr->sci' as it is part of
devm-allocated memory.
