Ubuntu.comUB:CVE-2020-36778CVE-2020-36778
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.
