Manual code analysis or AI? I noticed it while reviewing the driver's range handling and then compared it with the MCP47A1 datasheet. AI was used as an aid during the analysis, but I manually verified the datasheet values, in_range() semantics, and the final patch before sending it. I don't have MCP47A1 hardware available, so the testing was limited to build and static checks. Thanks, Tuna
