md/raid1-10: fix casting from randomized structure in raid1_submit_write()
Following build error triggered while build with clang version 17.0.0 with W=1(this can't be reporduced with gcc 13.1.0): drivers/md/raid1-10.c:117:25: error: casting from randomized structure pointer type 'struct block_device *' to 'struct md_rdev *' 117 | struct md_rdev *rdev = (struct md_rdev *)bio->bi_bdev; | ^ Fix this by casting 'bio->bi_bdev' to 'void *', as it used to be. Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202306142042.fmjfmTF8-lkp@intel.com/ Fixes: 8295efbe68c0 ("md/raid1-10: factor out a helper to submit normal write") Signed-off-by: Yu Kuai <yukuai3@huawei.com> Signed-off-by: Song Liu <song@kernel.org> Link: https://lore.kernel.org/r/20230616012136.3047071-1-yukuai1@huaweicloud.com
