T
Jean Delvare 2396d5cab7 Enhance w83791d support. Add output for in7, in8, in9, fan4 and fan5. 
Also update to display the (beep) properly due to the fact that the
w83791d beep enable mask is different than the alarm mask.
Patch from Sven Anders and Charles Spirakis.

/* There are some complications in a module like this. First off, W83781D chips
may be both present on the SMBus and the ISA bus, and we have to handle
those cases separately at some places. Second, there might be several
W83781D chips available (well, actually, that is probably never done; but
it is a clean illustration of how to handle a case like that). Finally,
a specific chip may be attached to *both* ISA and SMBus, and we would
not like to detect it double. Fortunately, in the case of the W83781D at
least, a register tells us what SMBus address we are on, so that helps
a bit - except if there could be more than one SMBus. Groan. No solution
for this yet. */

put a maximum of *nrels elements in results reflecting the data of this
