New Revision: 237195
URL: http://svn.freebsd.org/changeset/base/237195

Log:
  The variable 'error' in sys_poll() is initialized in declaration to value
  zero but in any case is overwritten by successive copyin(), making the
  previous initialization useless. Remove this.
  As an added bonus this fixes a style(9) bug.
