Switch the samsung_pwm_lock to the\nraw_spinlock, which remains a true non-sleeping spinlock even\nunder PREEMPT_RT.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/3b212f9d70805d91febae01d618868f4860e267c","tags":[]},{"url":"https://git.kernel.org/stable/c/7eb5764d25c4ac7f5d126621660f7219b61fd2fd","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
