Subject: Eliminate unused variable in rpmpluginsAdd()
X-Git-Tag: tznext/4.11.0.1.tizen20130304~1200
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=92ccb5f822c6b8889dbb784182f5da82f88f6102;p=tools%2Flibrpm-tizen.git

Eliminate unused variable in rpmpluginsAdd()
- dlsym() can return NULL without it being an error, and since we
  use dlerror() for determining the error anyway, supportedHooks
  is simply unneeded here.
