[PATCH 5.19 37/48] i2c: davinci: fix PM disable depth imbalance in davinci_i2c_probe

[Greg Kroah-Hartman]

From: Zhang Qilong <zhangqilong3@xxxxxxxxxx>

[ Upstream commit e2062df704dea47efe16edcaa2316d7b5ecca64f ]

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: 17f88151ff190 ("i2c: davinci: Add PM Runtime Support")
