Merge tag 'platform-drivers-x86-v5.4-3' of git://git.infradead.org/linux-platform-drivers-x86

Pull x86 platform driver fixes from Andy Shevchenko:

 - Users of Intel P-Unit IPC driver might be surprised by harmless
   warning. Thus, switch to API which doesn't issue a warning at all.

 - I²C multi-instantiate driver continues to add slave devices even when
   IRQ resource is not found. For devices in the market IRQ resource is
   mandatory, so, fail the ->probe() of the parent driver to avoid
   slaves being probed.

 - Avoid compiler warning due to unused variable in Classmate laptop
   driver.

* tag 'platform-drivers-x86-v5.4-3' of git://git.infradead.org/linux-platform-drivers-x86:
  platform/x86: i2c-multi-instantiate: Fail the probe if no IRQ provided
  platform/x86: intel_punit_ipc: Avoid error message when retrieving IRQ
  platform/x86: classmate-laptop: remove unused variable
