If anyone has any objections, please let me know. ------------------ From: Guenter Roeck commit f366fccd0809f13ba20d64cae3c83f7338c88af7 upstream. We read the chip ID from the chip, use it to determine if the chip ID provided to the driver is correct, and report it if wrong. We should also use the correct chip ID to select supported functionality.
