lib/logic_iomem: Fix 32-bit build
On a 32-bit build, the (unsigned long long) casts throw warnings (or errors) due to being to a different integer size. Cast to uintptr_t first (with the __force for sparse) and then further to get the consistent print on 32 and 64-bit. Fixes: ca2e334232b6 ("lib: add iomem emulation (logic_iomem)") Reported-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Richard Weinberger <richard@nod.at>
