my device driver work ok with intel i2c controller driver 1.1.1.1004(2015.8.18), driver name is "I2C Controller",

when i upgrade the i2c controller drver to 10.1.1.38(2016.10.3), driver name is "Interl(r) atom/celeron/pentium processor serial IO(SIO) - I2C Port 1 - 0F41",

my device driver can not start, error code is 51, waiting for following device start: ACPI\80860F41\1, ACPI\INT33FC\3.

but the new I2C driver is started already.
