Subject: iwlwifi: mvm: spin off a function to start scan offload
X-Git-Tag: v5.15~16721^2~28^2~17^2~122
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b141c23581164bfa7eb5eb19c2f00cb303c70d3b;p=platform%2Fkernel%2Flinux-starfive.git

iwlwifi: mvm: spin off a function to start scan offload

The net-detect feature will require a scan offload to be started in
the same way it is done now for scheduled scan.  Spin a new function
off of the sched_scan_start op code for reuse.  Additionally,
restructure the function a bit for more readability.
