[PATCH 5.10 124/390] spi: dw: Fix PM disable depth imbalance in dw_spi_bt1_probe

[Greg Kroah-Hartman]

From: Zhang Qilong <zhangqilong3@xxxxxxxxxx>

[ Upstream commit 618d815fc93477b1675878f3c04ff32657cc18b4 ]

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:abf00907538e2 ("spi: dw: Add Baikal-T1 SPI Controller glue driver")
