Provides: udev-extra-rules = %{version}-%{release}

That is implicit - it's name=version-release

Obsoletes: system-tuning-common-SUSE = 0.1-0

Also: for a package rename you want to be sure to either provide this symbol or make sure nothing requires it

oh and one more thing sorry - Obsoletes: system-tuning-common-SUSE = 0.1-0 - This release was never ever existing in any product

TW at the moment ships version 0.1 release 6.1 (-0 is never being produced inside OBS)

You should probably do:

Provides: system-tuning-common-SUSE = 0.1
Obsoletes: system-tuning-common-SUSE <= 0.1

(ignore the rpmlint warning)
