soc: ti: wkup_m3_ipc: Fix IRQ check in wkup_m3_ipc_probe
[ Upstream commit c3d66a164c726cc3b072232d3b6d87575d194084 ]
platform_get_irq() returns negative error number instead 0 on failure.
And the doc of platform_get_irq() provides a usage example:
int irq = platform_get_irq(pdev, 0);
if (irq < 0)
return irq;
Fix the check of return value to catch errors correctly.
