My gcc is brain dead here and outputs
CC [M] drivers/net/wireless/b43/phy_n.o
drivers/net/wireless/b43/phy_n.c: In function ‘b43_nphy_channel_setup.isra.14’:
drivers/net/wireless/b43/phy_n.c:4075:2: warning: ‘pmu_ctl’ may be used
uninitialized in this function [-Wuninitialized]
drivers/net/wireless/b43/phy_n.c:4029:6: note: ‘pmu_ctl’ was declared here
The variable is clearly set in all paths, but I still get the warning.
