I can see the same problem with Nokia N950 (which uses spi connected
wl1271). v4.4 + wl12xx spi DT patches from Uri Mashiach worked, v4.5
+ the same patches does not work. I currently suspect 133b7326e960
or 3719c17e1816 to be the culprit. I have not yet verified it, though.
Have you tried to bisect the problem?
