From 7287275b4301e230be9e4569431c7dacb67ebc13 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 4 Mar 2019 20:38:29 +0100 Subject: [PATCH] regulator: add regulator_get_linear_step() stub helper The regulator header has empty inline functions for most interfaces, but not regulator_get_linear_step(), which has just grown a user that does not depend on regulators otherwise: drivers/clk/tegra/clk-tegra124-dfll-fcpu.c: In function 'get_alignment_from_regulator': drivers/clk/tegra/clk-tegra124-dfll-fcpu.c:555:19: error: implicit declaration of function 'regulator_get_linear_step'; did you mean 'regulator_get_drvdata'? [-Werror=implicit-function-declaration] align->step_uv = regulator_get_linear_step(reg); ^~~~~~~~~~~~~~~~~~~~~~~~~ regulator_get_drvdata cc1: all warnings being treated as errors scripts/Makefile.build:278: recipe for target 'drivers/clk/tegra/clk-tegra124-dfll-fcpu.o' failed Add the missing stub along the others.
