Unfortunately this new change wasn't really based on a good understanding of the subsystem APIs and bypassed the usual patch flow without ensuring it was reviewed by people with subsystem knowledge and was merged as a fix rather than during the merge window. The effect of the new fix is to upgrade what were previously warnings on static data in the code to hard errors on that data. If this actually happens then it would break existing systems, if it doesn't happen then the change has no effect so this was not a safe change to apply as a fix to the release candidates. Since the new code has not been tested and doesn't in practice improve error handling revert it instead, and also drop the original revert since the original fix was fine. This takes the driver back to what it was in -rc1.

On resume the interrupts are re-enabled already by the io_init routine so we only clear the flag. The code is slightly different from the other codecs since the interrupt callback deals with the SDCA interrupts, leading to a much larger section that's protected by the mutex. The SoundWire interrupt scheme requires a read after clearing a status, it's not clear from the specifications what would happen if SDCA interrupts are disabled in the middle of the sequence, so the entire interrupt status read/write is kept as is, even if in the end we discard the information.
