Subject: rtlwifi: rtl8192cu: Add missing case in rtl92cu_get_hw_reg
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=16a4ea506503343a066e9b986e4775bf472e5205;p=openwrt%2Fstaging%2Fblogic.git

rtlwifi: rtl8192cu: Add missing case in rtl92cu_get_hw_reg

Driver was reporting 'switch case not processed' after association,
so HW_VAR_KEEP_ALIVE was added and filled similarily to other drivers.

Positive side effect to this seems to be a bit more stable connection.
