[alsa-devel] SB16 build error.

Found on a MIPS build but certain other architectures will have the same
sound/isa/sb/sb16_csp.c: In function ‘snd_sb_csp_ioctl’:
sound/isa/sb/sb16_csp.c:228: error: case label does not reduce to an integer constant
make: *** [sound/isa/sb/sb16_csp.o] Error 1
make: *** [sound/isa/sb/sb16_csp.o] Error 2
This error message is caused by the _IOC_TYPECHECK() error check triggering
due to excessive ioctl size on Alpha, PowerPC, MIPS and SPARC which define
_IOC_SIZEBITS as 13. On all other architectures define it as 14 so struct
snd_sb_csp_microcode with it's little over 12kB will just about fit into
the 16kB limit.
