Subject: [PATCH] dm cache policy smq: make static read-only array table const
Git-commit: 302f035141d3d4faee36f8543d34a32fb36a886d
Patch-mainline: v5.18-rc1
References: jsc#PED-2765
The 'table' static array is read-only so it make sense to make
it const. Add in the int type to clean up checkpatch warning.
