platform-drivers-x86 for v5.4-3

Browse Source 
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.
 
 The following is an automated git shortlog grouped by driver:
 
 classmate-laptop:
  -  remove unused variable
 
 i2c-multi-instantiate:
  -  Fail the probe if no IRQ provided
 
 intel_punit_ipc:
  -  Avoid error message when retrieving IRQ

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.
