(Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

The numbers specified in this array represent indices of the LED strings that are to be enabled and disabled. Its value is appropriately used to setup and enable string modules, but completely disregarded in the set_brightness paths which only iterate over the number of strings linearly. Take an example where only string 2 is enabled with qcom,enabled_strings=<2>: this string is appropriately enabled but subsequent brightness changes would have only touched the zero'th brightness register because num_strings is 1 here. This is simply addressed by looking up the string for this index in the enabled_strings array just like the other codepaths that iterate over num_strings. Likewise enabled_strings is now also used in the autodetection path for consistent behaviour: when a list of strings is specified in DT only those strings will be probed for autodetection, analogous to how the number of strings that need to be probed is already bound by qcom,num-strings. After all autodetection uses the set_brightness helpers to set an initial value, which could otherwise end up changing brightness on a different set of strings.
