If anyone has any objections, please let me know. ------------------ From: Alexander Sverdlin commit 0a8237ae319ab5988d40a7a9b33d68846aae34b4 upstream. pca9541 and pca954x are calling master_xfer() of the parent adapter directly thus bypassing the quirks checks of the adapter. Use __i2c_transfer() instead.
