Both functions are currently only called by void functions, which don't check on the return values of the functions. 
Nonetheless I think rtl8723a_set_rssi_cmd and rtl8723a_set_raid_cmd should return correct values and another patch should take on the calling void functions error handling.
As I'm not fully familiar with the inner workings of the driver, I'd leave the error handling for somebody else to implement, or would take it on later.
