ADAU1373_BCLKDIV_SOURCE is defined as BIT(5) which uses UL constants. On amd64 the result of the ones complement operator is then truncated to unsigned int according to the prototype of snd_soc_update_bits(). I think gcc is correctly warning that the upper 32 bits are lost.
sound/soc/codecs/adau1373.c: In function 'adau1373_hw_params': sound/soc/codecs/adau1373.c:940:3: warning: large integer implicitly truncated to unsigned type [-Woverflow]
gcc version 4.6.3
