Subject: [PATCH 8/9] usb: dwc3: Remove impossible check for of_clk_get_parent_count() < 0
Date: Mon, 22 Feb 2016 12:54:46 -0800 [thread overview]
Message-ID: <1456174487-28397-9-git-send-email-sboyd@codeaurora.org> (raw)
In-Reply-To: <1456174487-28397-1-git-send-email-sboyd@codeaurora.org>
The check for < 0 is impossible now that
of_clk_get_parent_count() returns an unsigned int. Simplify the
code and update the types.
