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.
