In the Linux kernel, the following vulnerability has been resolved:
i2c: sprd: fix reference leak when pmruntimeget_sync fails
The PM reference count is not expected to be incremented on return in sprdi2cmasterxfer() and sprdi2c_remove().
However, pmruntimeget_sync will increment the PM reference count even failed. Forgetting to putting operation will result in a reference leak here.
Replace it with pmruntimeresumeandget to keep usage counter balanced.
