With gcc 4.7.x, the following warning is issued as the routine that sets
the array has the possibility of not initializing the values:
CC [M] drivers/net/wireless/rtlwifi/rtl8192se/phy.o
drivers/net/wireless/rtlwifi/rtl8192se/phy.c: In function ‘rtl92s_phy_set_txpower’:
drivers/net/wireless/rtlwifi/rtl8192se/phy.c:1268:23: warning: ‘ofdmpowerLevel[0]’ may be used uninitialized in this function [-Wuninitialized]

John,
This problem exists for all versions of rtl8192se, but earlier compiler
versions did not detect it. For that reason, I am recommending this patch
be applied to 3.6.
