+Subject: [PATCH] sensors-detect: Fix the driver for Nuvoton W83677HG-I
+
+Originally, support for the Nuvoton W83677HG-I and derivatives was
+first added to the w83627ehf driver, so that's the driver recommended
+by sensors-detect. Later, support for the same device was added to
+the nct6775 driver. In kernel v5.6, support was removed from the
+w83627ehf driver to get rid of the duplicate code.
+
+So sensors-detect should now point users of this device to the
+nct6775 driver. We can't do that for very old kernels though, as this
+driver did not exist back then. I chose v3.10 for the cut-over, as
+this is when support for the Nuvoton W83677HG-I was finalized in the
+nct6775 driver, at least according to git log.
