From 0633e123465b61a12a262b742bebf2a9945f7964 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 1 Feb 2016 17:29:45 +0100 Subject: target/user: Fix cast from pointer to phys_addr_t The uio_mem structure has a member that is a phys_addr_t, but can be a number of other types too. The target core driver attempts to assign a pointer from vmalloc() to it, by casting it to phys_addr_t, but that causes a warning when phys_addr_t is longer than a pointer: drivers/target/target_core_user.c: In function 'tcmu_configure_device': drivers/target/target_core_user.c:906:22: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] This adds another cast to uintptr_t to shut up the warning. A nicer fix might be to have additional fields in uio_mem for the different purposes, so we can assign a pointer directly.
