Subject: [PATCH 1/3] mtd: onenand: samsung: Fix pointer cast -Wpointer-to-int-cast warnings on 64 bit
Date: Sun, 29 Dec 2019 19:36:10 +0100 [thread overview]
Message-ID: <20191229183612.22133-1-krzk@kernel.org> (raw)
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) {
