If I remove the cast to (void *), I got below build warning:

  CC      drivers/regulator/core.o
drivers/regulator/core.c: In function '_regulator_do_set_voltage':
drivers/regulator/core.c:2183:10: warning: passing argument 3 of
'_notifier_call_chain' makes pointer from integer without a cast
[enabled by default]
drivers/regulator/core.c:94:13: note: expected 'void *' but argument is
of type 'long unsigned int'
