AI-suggested
A fix is available and has been applied in the Linux kernel. The mutex initialization was added before backend registration. Users should update to the fixed kernel versions identified by the commits dec6193cef07e5915da0d6dd17725292d469e4aa, b473ee29aa0d39e7a7568b9675b15db2b0ae6057, and 549b71ce050637dd32678371ad76c445a2f8c9aa or later.
Description
A vulnerability in the Linux kernel's adi-axi-adc driver was fixed by initializing a state mutex that was previously uninitialized during probe. This mutex protects AXI ADC register access paths to serialize transactions, preventing potential race conditions.
