From: kbuild test robot <lkp@intel.com>

drivers/devfreq/governor_passive.c:336:7-13: inconsistent IS_ERR and PTR_ERR on line 337.

 PTR_ERR should access the value just tested by IS_ERR

Semantic patch information:
 There can be false positives in the patch case, where it is the call to
 IS_ERR that is wrong.

Hello,

This provides a patch, but it doesn't look like the right one.  It looks
like the if test should be testing opp_table,
