CVE-2020-36778

Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: xiic: fix reference leak when pm_runtime_get_sync fails
The PM reference count is not expected to be incremented on return in xiic_xfer and xiic_i2c_remove.
However, pm_runtime_get_sync will increment the PM reference count even failed. Forgetting to putting operation will result in a reference leak here.
Replace it with pm_runtime_resume_and_get to keep usage counter balanced.
