From: "Mark A. Greer" <mgreer@xxxxxxxxxxxxxxx>
It appears that the error paths were overlooked when the
omap3_pm_init() routine had the prcm chain handler code
added. Fix this by adding a goto target and reordering
the error handling code. Also fix how the irq argument
for free_irq() is determined.
