Subject: hwmon: (f71805f) Fix clamping of temperature limits
From: Jean Delvare <[email protected]>
commit 86b2bbfdbd1fcc4a3aa62ccd3f245c40c5ad5b85 upstream.
Properly clamp temperature limits set by the user. Without this fix,
attempts to write temperature limits above the maximum supported by
the chip (255 degrees Celsius) would arbitrarily and unexpectedly
result in the limit being set to 0 degree Celsius.
