+Subject: md/raid1-10: fix casting from randomized structure in raid1_submit_write()
+
+From: Yu Kuai <yukuai3@huawei.com>
+
+commit b5a99602b74bbfa655be509c615181dd95b0719e upstream.
+
+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>
