From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stephen Boyd Date: Mon, 22 Feb 2016 20:54:47 +0000 Subject: [PATCH 9/9] simplefb: Remove impossible check for of_clk_get_parent_count() < 0 Message-Id: <1456174487-28397-10-git-send-email-sboyd@codeaurora.org> List-Id: References: <1456174487-28397-1-git-send-email-sboyd@codeaurora.org> In-Reply-To: <1456174487-28397-1-git-send-email-sboyd@codeaurora.org> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Michael Turquette , Stephen Boyd Cc: linux-kernel@vger.kernel.org, linux-clk@vger.kernel.org, Hans de Goede , Jean-Christophe Plagniol-Villard , Tomi Valkeinen , linux-fbdev@vger.kernel.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.
