[PATCH 5.17 075/298] clocksource/drivers/oxnas-rps: Fix irq_of_parse_and_map() return value

[Greg Kroah-Hartman]

From: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>

[ Upstream commit 9c04a8ff03def4df3f81219ffbe1ec9b44ff5348 ]

The irq_of_parse_and_map() returns 0 on failure, not a negative ERRNO.
