Description

In the Linux kernel, the following vulnerability has been resolved:

i2c: img-scb: fix reference leak when pm_runtime_get_sync fails

The PM reference count is not expected to be incremented on return in functions img_i2c_xfer and img_i2c_init.

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.
