[PATCH] regulator/mfd: fix pointer-to-int cast

[Arnd Bergmann]

gcc points out that a pointer is longer than an int on 64-bit
architectures, and that casting between the two may be dangerous:

drivers/mfd/rohm-bd718x7.c: In function 'bd718xx_i2c_probe':
drivers/mfd/rohm-bd718x7.c:101:23: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]

In this driver it is correct, we just need the right kind of cast
to avoid the warning.

Fixes: 494edd266b94 ("regulator/mfd: Support ROHM BD71847 power management IC")
