max8997 cleanup bug?

[Dr. David Alan Gilbert]

Hi Lee,
  I noticed that:
   drivers/mfd/max8997-irq.c    max8997_irq_exit
isn't called anywhere and was about to send a deadcode patch,
but I'm thinking it's actually a bug and it should be called.

  Looking at the max8998, it has basically the same function,
and it calls it from an error path in it's max8998_i2c_probe.
There's no equivalent call in max8997's probe.

  To me it looks like it probably goes after the 'err_i2c_haptic:'
label, but I don't know the code and as far as I know I don't
have one of the devices.

  Any thoughts?

Dave
