Subject: [PATCH 5.19 267/717] spi/omap100k:Fix PM disable depth imbalance in omap1_spi100k_probe

From: Zhang Qilong <zhangqilong3@...wei.com>

[ Upstream commit 29f65f2171c85a9633daa380df14009a365f42f2 ]

The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced according to context.

Fixes:db91841b58f9a ("spi/omap100k: Convert to runtime PM")
