In the Linux kernel, the following vulnerability has been resolved: regulator: axp20x: AXP717: set rampdelay AXP717 datasheet says that regulator ramp delay is 15.625 us/step, which is 10mV in our case. Add a AXPDESCRANGESDELAY macro and update AXPDESCRANGES macro to expand to AXPDESCRANGESDELAY with rampdelay = 0 For DCDC4, steps is 100mv Add a AXPDESCDELAY macro and update AXPDESC macro to expand to AXPDESCDELAY with rampdelay = 0 This patch fix crashes when using CPU DVFS.
