ARM: OMAP2+: avoid NULL pointer dereference
For OMAP4, volt_data is set in omap44xx_voltagedomains_init. If the SoC is neither OMAP443X or OMAP446X, we end up with a NULL in volt_data which causes a kernel oops. This is the case when booting OMAP4470. Signed-off-by: Nicolae Rosia <Nicolae_Rosia@mentor.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
