3.13.11-ckt24 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexander Sverdlin <alexander.sverdlin@xxxxxxxxx>
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.
