FYI, my code checkers found this in this driver:

    SMATCH
drivers/gpio/gpio-pca953x.c:562 pca953x_irq_pending() error: buffer overflow 'cur_stat' 5 <= 8191
drivers/gpio/gpio-pca953x.c:573 pca953x_irq_pending() warn: buffer overflow 'old_stat' 5 <= 8191

Didn't check further. I fixed a sparse warning, though.
