pca955x_get_led() and pca955x_set_led() accept led indices equal to
pin_count, but valid indices are 0..pin_count-1. For a 16-pin device,
led16 passes the current check and then accesses an LS register past
max_reg.
Use the same >= pin_count bounds check as pca9554_set_pin() and the
gpio input handler assert in this file.
