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' ( Sorry, I forgot to reply-all so I send the mail again ) Axel -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
