[PATCH v3 3/3] net: xilinx: axienet: Propagate errors from platform_get_irq()

[phucduc . bui]

From: bui duc phuc <phucduc.bui@xxxxxxxxx>

platform_get_irq() returns a non-zero IRQ number on success and a
negative error number on failure. Therefore, 0 should not be treated
as an invalid IRQ number.

Propagate the original error code instead of overwriting it with
-ENOMEM.

Remove the redundant error message since platform_get_irq() already
reports errors when the IRQ lookup fails.
