Subject: [PATCH AUTOSEL 6.8 07/23] HID: mcp-2221: cancel delayed_work only when CONFIG_IIO is enabled

From: Abdelrahman Morsy <abdelrahmanhesham94@...il.com>

[ 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.
