ssd130x_update_bl() runs for every SSD13xx panel, but it only works for SSD130x and SSD132x: it writes the single global SSD13XX_CONTRAST (0x81) command, which those two families expose. SSD133x has no such command -- it has three per-channel contrast registers (CONTRAST_A/B/C) that must be scaled together -- so ssd130x_update_bl() has no effect on it. Make backlight_ops.update_status a per-family choice. SSD130x and SSD132x keep ssd130x_update_bl() because they share the SSD13XX_CONTRAST interface, while SSD133x gets ssd133x_update_bl(), which drives the three channels through ssd133x_set_contrast().
