[PATCH 5.10 076/717] spi: spi-ti-qspi: fix reference leak in ti_qspi_setup

[Greg Kroah-Hartman]

From: Zhang Qilong <zhangqilong3@xxxxxxxxxx>

[ Upstream commit 45c0cba753641e5d7c3207f04241bd0e7a021698 ]

pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to pm_runtime_put_noidle will result in
reference leak in ti_qspi_setup, so we should fix it.
