From: Krzysztof Kozlowski <krzk@kernel.org>

Subsystem:
memory technology devices (mtd), nand flash subsystem, onenand flash driver, the rest · Maintainers:
Miquel Raynal, Richard Weinberger, Vignesh Raghavendra, Kyungmin Park, Linus Torvalds
iomem pointers should be casted to unsigned long to avoid
-Wpointer-to-int-cast warnings when compiling on 64-bit platform (e.g.
with COMPILE_TEST):
drivers/mtd/nand/onenand/samsung_mtd.c: In function ‘s3c_onenand_readw’:
drivers/mtd/nand/onenand/samsung_mtd.c:251:6: warning:
cast from pointer to integer of different size [-Wpointer-to-int-cast]
if ((unsigned int) addr < ONENAND_DATARAM && onenand->bootram_command) {
