[PATCH 7/7] staging: r8188eu: RFType type is always ODM_1T1R

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
