Willem de Bruijn 5892138e30 hexagon: fix using plain integer as NULL pointer warning in cmpxchg ... [ Upstream commit 8a20030038 ] Sparse reports net/ipv4/inet_diag.c:1511:17: sparse: sparse: Using plain integer as NULL pointer Due to this code calling cmpxchg on a non-integer type struct inet_diag_handler * return !cmpxchg((const struct inet_diag_handler**)&inet_diag_table[type], NULL, h) ? 0 : -EEXIST; While hexagon's cmpxchg assigns an integer value to a variable of this type. __typeof__(*(ptr)) __oldval = 0; Update this assignment to cast 0 to the correct type. The original issue is easily reproduced at head with the below block, and is absent after this change. make LLVM=1 ARCH=hexagon defconfig make C=1 LLVM=1 ARCH=hexagon net/ipv4/inet_diag.o Fixes: 99a70aa051 ("Hexagon: Add processor and system headers") Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202411091538.PGSTqUBi-lkp@intel.com/ Signed-off-by: Willem de Bruijn <willemb@google.com> Tested-by: Christian Gmeiner <cgmeiner@igalia.com> Link: https://lore.kernel.org/r/20241203221736.282020-1-willemdebruijn.kernel@gmail.com Signed-off-by: Brian Cain <bcain@quicinc.com> Signed-off-by: Brian Cain <brian.cain@oss.qualcomm.com> Signed-off-by: Sasha Levin <sashal@kernel.org>		2025-02-08 09:58:11 +01:00
