  "details": "In the Linux kernel, the following vulnerability has been resolved:  pwm: lpc32xx: Remove handling of PWM channels  Because LPC32xx PWM controllers have only a single output which is registered as the only PWM device/channel per controller, it is known in advance that pwm-\u003ehwpwm value is always 0. On basis of this fact simplify the code by removing operations with pwm-\u003ehwpwm, there is no controls which require channel number as input.  Even though I wasn't aware at the time when I forward ported that patch, this fixes a null pointer dereference as lpc32xx-\u003echip.pwms is NULL before devm_pwmchip_add() is called.",
