Subject: ARM: tegra: cardhu: Correct interrupt trigger type of temperature sensor
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d8b17f31f12d9433f5cc636788e60c67bc701362;p=linux.git

ARM: tegra: cardhu: Correct interrupt trigger type of temperature sensor

The LM90 temperature sensor should use edge-triggered interrupt because
LM90 hardware doesn't deassert interrupt line until temperature is back
to normal state, which results in interrupt storm. Correct the interrupt
trigger type.
