The PM reference count is not expected to be incremented on return in ipi2c_imx_master_enable(). However, pm_runtime_get_sync() will increment the PM reference count even on failure. forgetting to put the reference again will result in a leak. Replace it with pm_runtime_resume_and_get() to keep the usage counter balanced.
