PATCH 1/1 build fix for sound/drivers/pcsp/pcsp.c

x86.git testing found the following build error in v2.6.26-rc1:

sound/drivers/pcsp/pcsp.c: In function 'pcsp_suspend':
sound/drivers/pcsp/pcsp.c:201: error: implicit declaration of function 'snd_pcm_suspend_all'

with the following config:

http://redhat.com/~mingo/misc/config-Sun_May__4_19_20_01_CEST_2008.bad

the reason is the .suspend callback - which is defined even in the case of !CONFIG_PM in which case snd_pcm_suspend_all() is not available. Undefine the method for that case, like other platform drivers do.
