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.
