[linux-pm] RTPM allowing trailing newline in state_store()

[dgollub at suse.de (Daniel Gollub)]

hi,

is there a special way reserved for writing on power/state in the device
directories?
a simple echo {0,1,2,3} doesn't work, because of the trailing newline.
only with echo -n it works.
i was very confused about that... i needed two days to figure this out

maybe it's a good idea to allow an value with   .. because other state
files like /sys/power/state also allows trailing newlines.

can you please give me a hint, if there is another special way to set a
single device in suspend. or is there a reason for ignoring trailing
newline?

(bbtw i send this mail a second time, because it wasn't delivered... but
can be found in archive)

thanks,
ddaniel
