Subject: [PATCH v5 4/5] wcn36xx: Implement print_reg indication
Date: Mon, 14 Nov 2016 22:06:53 -0800 [thread overview]
Message-ID: <1479190014-11297-4-git-send-email-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <1479190014-11297-1-git-send-email-bjorn.andersson@linaro.org>
Some firmware versions sends a "print register indication", handle this
by printing out the content.
