Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

regulator: axp20x: AXP717: set ramp_delay

AXP717 datasheet says that regulator ramp delay is 15.625 us/step, which is 10mV in our case.

Add a AXP_DESC_RANGES_DELAY macro and update AXP_DESC_RANGES macro to expand to AXP_DESC_RANGES_DELAY with ramp_delay = 0

For DCDC4, steps is 100mv

Add a AXP_DESC_DELAY macro and update AXP_DESC macro to expand to AXP_DESC_DELAY with ramp_delay = 0

This patch fix crashes when using CPU DVFS.
