Thanks Linus. I think the below patch(in fixes branch) should be merged into
devel branch too, since the below patch is depended by this one in devel branch.

gpio: pca953x: Use correct u16 value for register word write

the second byte is always 0. Change it to use cpu_to_le16
to write the two bytes into the register
