Revert "gpio: pca953x: initialize ret to zero to avoid returning garbage"
This reverts commit 313b9a99. This was already fixed by commit bf62efeb "gpio: pca954x: fix undefined error code from remove" The latter is a better fix since it makes it easier to detect erronous code by not assigning a default error code.
