Exiting early in remove without releasing all acquired resources yields leaks. Note that e.g. memory allocated with devm_zalloc() is freed after .remove() returns, even if the return code was negative.
While blocking_notifier_chain_unregister() won't fail and so the change is somewhat cosmetic, platform driver's .remove callbacks are about to be converted to return void. To prepare that, keep the error message but don't return early.

While I'm positive this change doesn't break anything, it also doesn't fix anything and is only cosmetic (+ preparing a later change).
Unless you need it as a dependency I'd say, don't backport it for stable.
Best regards Uwe
