Title
spi: fsl-lpspi: Fix PM reference leak in lpspi_prepare_xfer_hardware()
Summary
In the Linux kernel, the following vulnerability has been resolved: spi: fsl-lpspi: Fix PM reference leak in lpspi_prepare_xfer_hardware() pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. Fix it by replacing it with pm_runtime_resume_and_get to keep usage counter balanced.
