is this check even needed? I think the ACPI driver core takes care
of passing a valid ACPI device pointer to acpi_pcc_hotkey_remove().

I proceeded from the assumption that the current check was not redundant.
Kuppuswamy correctly noted in the message that the device would most likely be valid for the function of removal.

However, in my opinion, checking for NULL is a good coding practice, and has now been implemented incorrectly in this case.

Eliminating NULL checks could potentially cause bugs in this context.
