From: Peter Wu Date: Fri, 14 Feb 2014 18:03:44 +0000 (+0100) Subject: rtlwifi: avoid accessing RCR directly X-Git-Tag: firefly_0821_release~176^2~4167^2~18^2^2~262 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e51048cdf0bdf1358c39839eabb22a06674af9ed;p=firefly-linux-kernel-4.4.55.git rtlwifi: avoid accessing RCR directly The rtl*_set_check_bssid functions are mostly the same, but access the RCR register in different ways. Use the get_hw_reg abstraction layer (which reads rtlpci->receive_config for PCI devices and mac->rx_conf for USB). There is no functional change for cases where receive_config was accessed directly. For rtl8192ce, there is still no change because nothing modifies REG_RCR or receive_config. For rtl8192cu, it now also applies changes to rx_conf from configure_filter, but that can be considered a bug which is fixed later.
