[PATCH 4.9 060/271] thermal: mediatek: fix register index error

From: Greg Kroah-Hartman
Date: Tue Jan 28 2020 - 09:17:17 EST


From: Michael Kao <michael.kao@xxxxxxxxxxxx>

[ Upstream commit eb9aecd90d1a39601e91cd08b90d5fee51d321a6 ]

The index of msr and adcpnp should match the sensor
which belongs to the selected bank in the for loop.

Fixes: b7cf0053738c ("thermal: Add Mediatek thermal driver for mt2701.")
