    ARM: s3c24xx: enable CONFIG_BUG for tct_hammer · 15b5eb2d
    Arnd Bergmann authored
    Disabling CONFIG_BUG creates an insane amount of build warnings, which
    makes it useless to check for building defconfigs to see if new
    warnings show up.
    
    Without this patch, building tct_hammer_defconfig results in:
    
    net/packet/af_packet.c: In function 'tpacket_rcv':
    net/packet/af_packet.c:1889:30: warning: 'hdrlen' may be used uninitialized in this function [-Wuninitialized]

    (and many more)
