clk: ti: fix dual-registration of uart4_ick
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 Fixes: aafd900cab87 ("CLK: TI: add omap3 clock init file") Cc: stable@vger.kernel.org Cc: mturquette@baylibre.com Cc: sboyd@codeaurora.org Cc: linux-clk@vger.kernel.org Cc: linux-omap@vger.kernel.org Cc: linux-kernel@lists.codethink.co.uk Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Signed-off-by: Tero Kristo <t-kristo@ti.com>
