In the commit 3c8f4ad85c4b ("memory/mediatek: add support for mt2701"), the larbid was used without properly initialized. This patchset fixed that. Also include a patch which using the of_device_get_match_data helper to simplify the code. This patchset was base on 4.13-rc1. Change since v2: - Using compatible strings of "mediatek,larb-id" instead of "mediatek,larbid" to make it a bit easier to read. - Put the v2 of the patch ("memory: mtk-smi: Use of_device_get_match_data helper")[1] in this patchset to make the changes easier for review. - Add the reivewer's tag in commit messages. Change since v1: - Using mtk_smi_larb_gen to identify whether larbid was needed instead of checking hard code bindings.
