To be sure below issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, my Linux kernel regression tracking bot: #regzbot ^introduced c6f7874687f7027d7c4b2f53ff6e4d228 #regzbot title spi: mediatek: oops due to race #regzbot monitor: https://lore.kernel.org/all/Y6hZA19rWuDkGJa2@makrotopia.org/ #regzbot fix: spi: mediatek: Enable irq before the spi registration #regzbot ignore-activity Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I deal with a lot of reports and sometimes miss something important when writing mails like this. If that's the case here, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight.
