Subject: spi: dw: Fix PM disable depth imbalance in dw_spi_bt1_probe
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=daa5239ea49ff336460ead9f86c6c6c4e9557030;p=linux.git

spi: dw: Fix PM disable depth imbalance in dw_spi_bt1_probe

[ 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.
