3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Dooks <ben.dooks@codethink.co.uk>
commit 19e79687de22f23bcfb5e79cce3daba20af228d1 upstream.
On the OMAP AM3517 platform the uart4_ick gets registered twice, causing any power management to /dev/ttyO3 to fail when trying to wake the device up.
This solves the following oops:
[] Unhandled fault: external abort on non-linefetch (0x1028) at 0xfa09e008 [] PC is at serial_omap_pm+0x48/0x15c [] LR is at _raw_spin_unlock_irqrestore+0x30/0x5c
