When cross-compiling the 2.6.39 wireless-testing source using GCC version
(SUSE Linux) 4.3.2 [gcc-4_3-branch revision 141291] on an x86_64 system,
the following warning is issued:
CC [M] drivers/net/wireless/b43/phy_n.o
drivers/net/wireless/b43/phy_n.c: In function ‘b43_nphy_cal_tx_iq_lo’:
drivers/net/wireless/b43/phy_n.c:3096: warning: ‘last’ may be used
uninitialized in this function
A quick look at the code shows that the warning is bogus and a gcc bug,
but to ensure clean compilation for all users, mark the offending variable
as uninitialized.
