      powerpc: Fix memory leak in axon_msi.c · aee7a283
      Michael Ellerman authored
      
      
      cppcheck found a memory leak in axon_msi, if dcr_base or dcr_len are zero,
      we have already allocated msic, so we should free it in the error path.

      powerpc/pmac: Fix issues with sleep on some powerbooks · 11a50873
      Benjamin Herrenschmidt authored
      
      
      Since the change of how interrupts are disabled during suspend,
      certain PowerBook models started exhibiting various issues during
      suspend or resume from sleep.
      
      I finally tracked it down to the code that runs various "platform"
      functions (kind of little scripts extracted from the device-tree),
      which uses our i2c and PMU drivers expecting interrutps to work,
      and at a time where with the new scheme, they have been disabled.
      
      This causes timeouts internally which for some reason results in
      the PMU being unable to see the trackpad, among other issues, really
      it depends on the machine. Most of the time, we fail to properly adjust
      some clocks for suspend/resume so the results are not always
      predictable.
      
      This patch fixes it by using IRQF_TIMER for both the PMU and the I2C
      interrupts. I prefer doing it this way than moving the call sites since
      I really want those platform functions to still be called after all
      drivers (and before sysdevs).
      
      We also do a slight cleanup to via-pmu.c driver to make sure the
      ADB autopoll mask is handled correctly when doing bus resets
