[PATCH 6.1.y] media: rkvdec: Propagate platform_get_irq() errors

[Sasha Levin <sashal@kernel.org>]

From: Narasimharao Vadlamudi <ahmisaranrao@gmail.com>

[ Upstream commit c37aca64206fafe938119e801a3fd10a537a051f ]

platform_get_irq() returns a positive IRQ number on success and a
negative error code on failure. It no longer returns zero. The driver
currently returns -ENXIO for all failures, which loses useful errors
such as -EPROBE_DEFER.

Return the error from platform_get_irq() directly.
