While fixing it, I rewrote the read function to make better use of the device node and device relationship. Patch 1 rewrites the cell read function in the mtk-socinfo so that no resource leaks happen, and device lookup is more efficient. Sidenote: I think the cell read function could be reworked a bit more to return different error codes for different failure modes. Patch 2 adds an extra socinfo entry for MT8183. It seems that some units have chips that have this one. At least mine does. Patch 3 drops the custom nvmem device name from the mtk-efuse driver. This was previously used for nvmem device lookup, but on MT8183 with two efuses, one would fail to probe due to this. Since after patch 1 this is no longer used, we can just drop it. Please merge. On the MT8183 ChromeOS devices this currently crashes.
