On basis of this fact simplify the code by removing operations with pwm-&gt;hwpwm, there is no controls which require channel number as input.</p> <p>Even though I wasn&#39;t aware at the time when I forward ported that patch, this fixes a null pointer dereference as lpc32xx-&gt;chip.pwms is NULL before devm_pwmchip_add() is called.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>pwm: lpc32xx: Remove handling of PWM channels</p> <p>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-&gt;hwpwm value is always 0.
