[PATCH v2 0/2] check I2C device id for pca984x chips

[Peter Rosin]

Hi!

This series tries to check the I2C device id, but instead of open
coding the check in the pca954x driver, I have a new function in
the core doing the work.

Changes since v1:
- Added Tested-by tag from Adrian
- Added Reviewed-by tag from Wolfram
- Replaced client->flags with a zero in the i2c_smbus_xfer call

Wolfram: I'll send a pull with the first patch in a few days, to
allow for a second round of feedback now that the RFC marker is gone.

Cheers,
peda

  i2c: add i2c_get_device_id() to get the standard i2c device id
  i2c: mux: pca954x: verify the device id of the pca984x chips
