From 86cf635a316e89ba6ae79f452cedb5acddccf570 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Thu, 17 Mar 2016 14:54:54 -0300 Subject: regulator: Rename files for Maxim PMIC drivers Most Maxim PMIC regulator drivers are for sub-devices of Multi-Function Devices with drivers under drivers/mfd. But for many of these, the same object file name was used for both the MFD and the regulator drivers. Having 2 different drivers with the same name causes a lot of confusion to Kbuild, specially if these are built as module since only one module will be installed and also exported symbols will be undefined due being overwritten by the other module during modpost. For example, it fixes the following issue when both drivers are module: $ make M=drivers/regulator/ ... CC [M] drivers/regulator//max14577.o Building modules, stage 2. MODPOST 1 modules WARNING: "maxim_charger_calc_reg_current" [drivers/regulator//max14577.ko] undefined! WARNING: "maxim_charger_currents" [drivers/regulator//max14577.ko] undefined!
