CVE-2025-37968

CVE-2025-37968 (Linux kernel) affects the iio: light: opt3001 driver. The issue is a deadlock in a threaded IRQ path caused by reading the same flag twice (once for mutex_lock, once for mutex_unlock). The fix standardizes the flag handling by reading it into a local variable and reusing that valu...
