Subject: mfd: axp20x: Do not sleep in the power off handler
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=3bcc06c5fd4842841763c398f301ea1291d0b653;p=users%2Fjedix%2Flinux-maple.git

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.

Fixes: 856c288b0039 ("ARM: Use do_kernel_power_off()")
