[PATCH 5.11 229/601] ARM: dts: qcom: msm8974-samsung-klte: correct fuel gauge interrupt trigger level

[Greg Kroah-Hartman]

From: Krzysztof Kozlowski <krzk@xxxxxxxxxx>

[ Upstream commit 5fde3361ba57a9b4eb560dabf859176909d61004 ]

The Maxim fuel gauge datasheets describe the interrupt line as active
low with a requirement of acknowledge from the CPU.  The falling edge
interrupt will mostly work but it's not correct.
