2.5.2 cmpci.c Compilation error

[Panagiotis Moustafellos <panxer@hol.gr>]

Dear sirs,
When i try to make bzImage the 2.5.2 kernel having enabled the following;
CONFIG_SOUND=y
CONFIG_SOUND_CMPCI=y
CONFIG_SOUND_CMPCI_FM=y
CONFIG_SOUND_CMPCI_FMIO=388
CONFIG_SOUND_CMPCI_FMIO=388
CONFIG_SOUND_CMPCI_MIDI=y
CONFIG_SOUND_CMPCI_MPUIO=330
CONFIG_SOUND_CMPCI_JOYSTICK=y
CONFIG_SOUND_CMPCI_CM8738=y
CONFIG_SOUND_CMPCI_SPDIFINVERSE=y
CONFIG_SOUND_CMPCI_SPDIFLOOP=y
CONFIG_SOUND_CMPCI_SPEAKERS=2

I get the following error;
cmpci.c: In function `cm_open_mixdev':
cmpci.c:1443: invalid operands to binary &
cmpci.c: In function `cm_release_mixdev':
cmpci.c:1457: warning: unused variable `s'
cmpci.c: In function `cm_open':
cmpci.c:2193: invalid operands to binary &
cmpci.c: In function `cm_midi_open':

and goes on for some more lines..
Is this a known bug? could it be that some options are conflicting?
Thanks in advance,
