Description
In the Linux kernel, the following vulnerability has been resolved:
i2c: stm32f7: fix reference leak when pm_runtime_get_sync fails
The PM reference count is not expected to be incremented on
return in these stm32f7_i2c_xx serious functions.
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.
Affected configurations
• linux linux kernel (>= 5.6 < 5.10.37)
• linux linux kernel (>= 5.11 < 5.11.21)
• linux linux kernel (>= 5.12 < 5.12.4)
