New Revision: 288452
URL: https://svnweb.freebsd.org/changeset/base/288452

Log:
  Most error cases in i915_gem_do_execbuffer() jump to one of two labels to
  release resources (such as unholding pages) when errors occur.  Some
  recently added error checks return immediately instead of jumping to a
  label resulting in leaks.  Fix these to jump to a label to do cleanup
  instead.
