This patch attempts to fix the following bug in KInfoCenter: https://bugs.kde.org/show_bug.cgi?id=380355 (Bug 380355 - Processors numbers listed are machine-sorted, not human-sorted in Device Viewer).
It overloads the < operator on the SolDevice class to implement sorting by process number and sorting by storage volume names (as they should go, e.g.: sda, sda1, sda2...).
Result:
{F3898778}
