Ubuntu.comUB:CVE-2020-36784CVE-2020-36784
In the Linux kernel, the following vulnerability has been resolved: i2c:
cadence: fix reference leak when pm_runtime_get_sync fails The PM reference
count is not expected to be incremented on return in functions
cdns_i2c_master_xfer and cdns_reg_slave. However, pm_runtime_get_sync will
increment pm usage counter 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.
