| Subject: clk: ti: fix dual-registration of uart4_ick |
| |
| 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 |
| |
