Description

In the Linux kernel, the following vulnerability has been resolved: iio: gyro: mpu3050-core: fix pm_runtime error handling The return value of pm_runtime_get_sync() is not checked, allowing the driver to access hardware that may fail to resume. The device usage count is also unconditionally incremented. Use pm_runtime_resume_and_get() which propagates errors and avoids incrementing the usage count on failure. In preenable, add pm_runtime_put_autosuspend() on set_8khz_samplerate() failure since postdisable does not run when preenable fails.
