[PATCH 3.16 024/134] PCI: dwc: Unindent dw_handle_msi_irq() loop

[Ben Hutchings]

3.16.47-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Bjorn Helgaas <bhelg...@google.com>

commit dbe4a09e8bbcf88809a8394d6a359d8cebd22a86 upstream.

Use "continue" to skip rest of the loop when possible to save an indent
level.  No functional change intended.
