| Subject: regulator: add regulator_get_linear_step() stub helper |
| |
| [ Upstream commit 7287275b4301e230be9e4569431c7dacb67ebc13 ] |
| |
| 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. |
| |
| Fixes: b3cf8d069505 ("clk: tegra: dfll: CVB calculation alignment with the regulator") |
