Subject[PATCH] regulator/tps6586x: silence pointer-to-int-cast
Date
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).
