From 5127e31a6ce04bd41a020c0ba28a1c0915ab6da1 Mon Sep 17 00:00:00 2001 From: "Suzuki K. Poulose" Date: Fri, 10 Jul 2015 16:26:38 +0100 Subject: regulator: Add missing dummy definition for regulator_list_voltage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes a build break when CONFIG_REGULATOR is not selected. e.g, on linux-next - 07102015: drivers/clk/tegra/clk-dfll.c: In function ‘find_lut_index_for_rate’: drivers/clk/tegra/clk-dfll.c:691:3: error: implicit declaration of function ‘regulator_list_voltage’ [-Werror=implicit-function-declaration] if (regulator_list_voltage(td->vdd_reg, td->i2c_lut[i]) == uv) ^ CC drivers/clocksource/mmio.o CC fs/proc/softirqs.o cc1: some warnings being treated as errors make[3]: *** [drivers/clk/tegra/clk-dfll.o] Error 1 make[2]: *** [drivers/clk/tegra] Error 2 make[1]: *** [drivers/clk] Error 2 make[1]: *** Waiting for unfinished jobs.... This should be pushed to 4.2 as we have the issue in 4.2-rc1, just that nobody uses it without the REGULATOR(yet). Signed-off-by: Suzuki K.
