[PATCH 4.9 034/139] backlight: sky81452-backlight: Fix refcount imbalance on error

[Greg Kroah-Hartman]

From: dinghao.liu@xxxxxxxxxx <dinghao.liu@xxxxxxxxxx>

[ Upstream commit b7a4f80bc316a56d6ec8750e93e66f42431ed960 ]

When of_property_read_u32_array() returns an error code, a
pairing refcount decrement is needed to keep np's refcount
balanced.
