[PATCH] media: pisp_be: Propagate platform_get_irq() errors

[Narasimharao Vadlamudi]

platform_get_irq() returns a non-zero IRQ number on success and a
negative error code on failure. The driver currently returns -EINVAL
for all failures, which loses useful errors such as -EPROBE_DEFER.

Return the error from platform_get_irq() directly.
