Description
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.
Affected configurations
• linux linux kernel (>= 5.7 < 5.10.37)
• linux linux kernel (>= 5.11 < 5.11.21)
• linux linux kernel (>= 5.12 < 5.12.4)
