6.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sean Anderson sean.anderson@linux.dev
commit 1315cc2dbd5034f566e20ddce4d675cb9e6d4ddd upstream.
AMS_ALARM_THR_DIRECT_MASK should be bit 0, not bit 1. This would cause hysteresis to be enabled with a lower threshold of -28C. The temperature alarm would never deassert even if the temperature dropped below the upper threshold.
