[PATCH 7/7] staging: r8188eu: RFType type is always ODM_1T1R
From: Michael Straube
Date: Tue Oct 19 2021 - 09:52:05 EST
This driver is for 1T1R chips. The field RfType of odm_dm_struct is
set to ODM_1T1R and never changed. Remove code that initializes RFType,
remove it from odm_dm_struct and remove resulting dead code.
