If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit bce3471dd02c7085d99dc200f2828a13c2d340a4 Author: Samuel Holland <samuel@xxxxxxxxxxxx> Date: Sat Nov 5 16:29:09 2022 -0500 mfd: axp20x: Do not sleep in the power off handler [ Upstream commit 3f37d4f695cff180033254b9ed5adc8ab927cba9 ] Since commit 856c288b0039 ("ARM: Use do_kernel_power_off()"), the function axp20x_power_off() now runs inside a RCU read-side critical section, so it is not allowed to call msleep(). Use mdelay() instead.
