Bootloader can leave interrupt bit pending, and it confuses driver.
OK, looks good to me. One question though, just to make sure everything is covered : Suppose that the resume is the consequence of keypad press. If anybody relied previously on "reading the keypad" to know which key was pressed to wakeup the SoC, is it still working after your patch ? And I suppose you can't "convince" your bootloader to behave correctly, can you ? Cheers. -- Robert
