Subject: [PATCH] dm clone: make array 'descs' static
Git-commit: ec132ef2d1d94d43d9dce1400521526bbed89a8b
Patch-mainline: v5.15-rc6
References: jsc#PED-2765

Don't populate the read-only array descs on the stack but instead it
static and add extra const. Also makes the object code smaller by 66
Bytes: 

Before: text    data     bss     dec     hex filename

After: text    data     bss     dec     hex filename
  42220   11236     512   53968    d2d0 ./drivers/md/dm-clone-target.o
