ARM: omap: fix address space warnings from sparse
Moving sram code from plat-omap got the attention of the kernel test robot. I found a few more places with related warnings because the sram references are a mix of kernel pointers and __iomem pointers: mach-omap1/sram-init.c:56:17: warning: cast removes address space '__iomem' of expression mach-omap1/board-ams-delta.c:667:9: warning: incorrect type in argument 1 (different base types) mach-omap2/sram.c:78:17: warning: cast removes address space '__iomem' of expression mach-omap2/omap4-common.c:142:27: warning: incorrect type in assignment (different address spaces) mach-omap2/omap4-common.c:142:27: expected void [noderef] __iomem *static [toplevel] sram_sync mach-omap2/omap4-common.c:142:27: got void * mach-omap2/pm34xx.c:113:45: warning: incorrect type in argument 1 (different address spaces) mach-omap2/pm34xx.c:113:45: expected void [noderef] __iomem *save_regs mach-omap2/pm34xx.c:113:45: got void *extern [addressable] [toplevel] omap3_secure_ram_storage There is no good solution here, as sram is a bit special in this regard. Change the annotations to at least shut up the warnings. Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
