From b7cec13f082fcc6e690559657d3f5493ea6eecb7 Mon Sep 17 00:00:00 2001 From: Dinh Nguyen Date: Fri, 13 Dec 2013 16:38:28 -0600 Subject: clk: socfpga: Look for the GPIO_DB_CLK by its offset After the patch: "clk: socfpga: Map the clk manager base address in the clock driver" The clk->name field in socfpga_clk_recalc_rate() was getting cleared. Replace looking for the GPIO_DB_CLK by its divider offset instead. Also rename the define SOCFPGA_DB_CLK_OFFSET -> SOCFPGA_GPIO_DB_CLK_OFFSET, as this represents the GPIO_DB_CLK.
