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
