Ubuntu.comUB:CVE-2020-36781CVE-2020-36781
In the Linux kernel, the following vulnerability has been resolved: i2c:
imx: fix reference leak when pm_runtime_get_sync fails In i2c_imx_xfer()
and i2c_imx_remove(), the pm reference count is not expected to be
incremented on return. However, pm_runtime_get_sync will increment 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.
