macro indices before updating state [ Upstream commit 95dffe32a66cbed07fbfa7afed39d56d5014e04f ] aiptek_irq() derives macro key indices directly from tablet reports and then uses them to index macroKeyEvents[]. Report types 4 and 5 also save the derived value in aiptek->lastMacro and later use that state to release the previous key. Validate the raw macro index once before it enters that state machine, so lastMacro only ever stores an in-range macro key. Keep direct bounds checks for report type 6, which reads the macro number from the packet body and uses it immediately.
