+Subject: [PATCH 14/42] thermal/drivers/mediatek/lvts_thermal: Fix sensor 1
+ interrupt status bitmask
+
+The binary representation for sensor 1 interrupt status was incorrectly
+assembled, when compared to the full table given in the same comment
+section. The conversion into hex was also incorrect, leading to
+incorrect interrupt status bitmask for sensor 1. This would cause the
+driver to incorrectly identify changes for sensor 1, when in fact it
+was sensor 0, or a sensor access time out.
+
+Fix the binary and hex representations in the comments, and the actual
+bitmask macro.
+
+Fixes: f5f633b18234 ("thermal/drivers/mediatek: Add the Low Voltage Thermal Sensor driver")
