Subject: [PATCH] iwlwifi: dbg_ini: use regions ops array instead of switch case in dump flow
Git-commit: cd6de838e179287cbbfb7b655701183f2d32936e
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430
Make a static regions ops array and use it instead of switch case when
determining what op to use to collect a region.
