Subject: Handle NULL and the same literal problem pointer in rpmProblemCompare()
X-Git-Tag: tznext/4.11.0.1.tizen20130304~2130
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=34ddaa716174e29c42f005e3546dbbeeb60c7057;p=tools%2Flibrpm-tizen.git

Handle NULL and the same literal problem pointer in rpmProblemCompare()
- if the pointers to compare are the same, the problem is the same
  (even if NULL for our purposes)
- if they're not the same and either is NULL then they're not the same
