From: Abdelrahman Morsy <abdelrahmanhesham94@xxxxxxxxx> [ Upstream commit 3cba9cfcc1520a2307a29f6fab887bcfc121c417 ] If the device is unplugged and CONFIG_IIO is not supported, this will result in a warning message at kernel/workqueue. Only cancel delayed work in mcp2221_remove(), when CONFIG_IIO is enabled.
