+Subject: [PATCH] clk: sunxi: factors: fix off-by-one masks
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The previous code would generate one bit too long masks, and was
+needlessly complicated. This patch replaces it by simpler code that can
+generate the masks correctly.
