| |
When attempting to configure this driver on a Nexus 5 phone (msm8974), setting up the dummy i2c bus for TX_P0 would fail due to an -EBUSY error. The downstream MSM kernel sources [1] shows that the proper value for TX_P0 is 0x78, not 0x70, so correct the value to allow device probing to succeed.
