Bastian Stender cfc5b2b551 fbdev/ssd1307fb: fix optional VBAT support ... SSD1306 needs VBAT when it is wired in charge pump configuration only. Other controllers of the SSD1307 family do not need it at all. This was introduced by commit ba14301e03 ("fbdev/ssd1307fb: add support to enable VBAT"). Without VBAT configuration the driver now fails with: failed to get VBAT regulator: -19 This is caused by misinterpretation of devm_regulator_get_optional which "returns a struct regulator corresponding to the regulator producer or IS_ERR() condition". Handle -ENODEV without bailing out and making VBAT support really optional.
