Merge tag 'gpio-v5.3-5' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO fixes from Linus Walleij:
 "All related to the PCA953x driver when handling chips with more than 8
  ports, now that works again"

* tag 'gpio-v5.3-5' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
  gpio: pca953x: use pca953x_read_regs instead of regmap_bulk_read
  gpio: pca953x: correct type of reg_direction
