From a70f0d027c83350ad46ca3e86e4c781bfed7fcc2 Mon Sep 17 00:00:00 2001 From: Daniel Kurtz Date: Wed, 22 Jul 2015 18:23:26 +0800 Subject: regulator: tps6586x: silence pointer-to-int-cast of_regulator_match.driver_data is (void *). tps6586x uses it to store an anonymous enum value (those TPS6586X_ID_ values). Later, it tries to extract the ID by casting directly to an int, which is a no-no ([-Wpointer-to-int-cast]): drivers/regulator/tps6586x-regulator.c: In function 'tps6586x_parse_regulator_dt': drivers/regulator/tps6586x-regulator.c:430:8: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] id = (int)tps6586x_matches[i].driver_data; ^ Instead of casting to int, uintptr_t is better suited for receiving and comparing integers extracted from void *. This is especially true on 64-bit systems where sizeof(void *) != sizeof(int).
