Merge tag 'platform-remove-void-step-b' of https://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux into driver-core-next

Uwe writes:

Change struct platform_driver::remove() to return void

This is step b) of the plan outlined in commit 5c5a7680e67b ("platform:
Provide a remove callback that returns no value"), which completes the
first major step of making the remove callback return no value. Up to
now it returned an int which however was mostly ignored by the driver
core and lured driver authors to believe there is some error handling.

Note that the Linux driver model assumes that removing a device cannot
fail, so this isn't about being lazy and not implementing error handling
in the core and so making .remove return void is the right thing to do.
