Subject[PATCH 4.9 060/271] thermal: mediatek: fix register index error
Date
From: Michael Kao <michael.kao@mediatek.com>

[ 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.")
