[ Upstream commit eb9aecd90d1a39601e91cd08b90d5fee51d321a6 ]

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

[ Upstream commit 15e14f76f85f4f0eab3b8146e1cd3c58ce272823 ]

Fix bbp ready check in mt7601u_wait_bbp_ready. The issue is reported by
coverity with the following error:

Logical vs. bitwise operator
The expression's value does not depend on the operands; inadvertent use
of the wrong operator is a likely logic error.

Addresses-Coverity-ID: 1309441 ("Logical vs. bitwise operator")
