Subject: [patch v2] spi: bcm63xx-hsspi: checking for ERR_PTR instead of NULL
Date: Fri, 6 Dec 2013 17:12:13 +0300 [thread overview]
Message-ID: <20131206141212.GA956@elgon.mountain> (raw)
In-Reply-To: <CAOiHx=k87c_bFqFtJ7zJc9HxnjOEr2oMofNUsLkQbfQPrC04hQ-JsoAwUIsXosN+BqQ9rBEUg@public.gmane.org>
devm_request_and_ioremap() returns NULL on error, it doesn't return an
ERR_PTR(). This patch fixes it by switching to devm_ioremap_resource()
which is the prefered function anyway.
Fixes: 142168eba9dc ('spi: bcm63xx-hsspi: add bcm63xx HSSPI driver')
