[v1] iio: adc: axp20x_adc: Add missing sentinel to AXP717 ADC channel maps

[PATCH] iio: adc: axp20x_adc: Add missing sentinel to AXP717 ADC channel maps

Posted by Chen-Yu Tsai 6 months, 2 weeks ago

From: Chen-Yu Tsai <wens@csie.org>

The AXP717 ADC channel maps is missing a sentinel entry at the end. This
causes a KASAN warning.

Add the missing sentinel entry.

Applied to my temporary fixes tree.  I'll rebase that on rc1 in next few days.
