[PATCH] remove untrusted chars read from sysfs-values or returned by PROGRAM
Better remove characters that are useless in a device node name.
It may be a security risk to pass any character read from e.g. a
sysfs attribute to a shell script we execute later.
Prevent the modification of the libsysfs attribute value
cache.
Clear PROGRAM result if the execution encountered an error.
