3.16.47-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>
commit dbe4a09e8bbcf88809a8394d6a359d8cebd22a86 upstream.
Use "continue" to skip rest of the loop when possible to save an indent
level. No functional change intended.
