the if/elseif/else is exhaustive - there is no 4th case given the
rssi_ctrl_mask = RADIO_2055_NBRSSI_SEL | RADIO_2055_WBRSSI_G1_SEL |
RADIO_2055_WBRSSI_G2_SEL;
so this unreachable else case (dead code) can be dropped.

It seems that there are only three cases:
RADIO_2055_NBRSSI_SEL | RADIO_2055_WBRSSI_G1_SEL | RADIO_2055_WBRSSI_G2_SEL
The conditional call to wlc_phy_rssisel_nphy(... NPHY_RSSI_SEL_*) thus do
not seem to have a 4th case which would be covered by the final else.
If the final else is there to accommodate extensions then this patch is
of course wrong - in that case it would be good though to comment the
final else as it appears to be dead-code at the moment.
Patch was only compile tested with x86_64_defconfig + CONFIG_BRCMSMAC=m
Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
