From: Linus Walleij linus.walleij@linaro.org
stable inclusion from stable-5.10.50 commit ea45145e6cb4f030ea6be7f442b0a470d1e31189 bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 7749510c459c10c431d746a4749e7c9cf2899156 upstream.
The Ux500 HREF LEDs have not been probing properly for a while as this was introduce:
ret = of_property_read_u32(np, "color", &led_color); if (ret) return ret;
Since the device tree did not define the new invented color attribute, probe was failing.
Define color attributes for the LEDs so they work again.
