[PATCH 3/3] staging: vt6656: Remove duplicate code in vnt_rf_table_download

From: Oscar Carter
Date: Sat Apr 25 2020 - 08:39:58 EST


Replace three while loops with three calls to the vnt_control_out_blocks
function. This way avoid repeat a functionality that already exists.

Also remove the variables that now are not used.
