From d7ddf5f4269fcaf19aafe971e635d91897423a3a Mon Sep 17 00:00:00 2001 From: Arkadiusz Kubalewski Date: Tue, 25 Jul 2023 12:16:41 +0200 Subject: tools: ynl-gen: fix enum index in _decode_enum(..) Remove wrong index adjustment, which is leftover from adding support for sparse enums. enum.entries_by_val() function shall not subtract the start-value, as it is indexed with real enum value.
