Subject: [PATCH] USB: gadget: udc: Remove some dead code
Git-commit: c326d3ed52c8b47f0de329b3b213dc32409d3656
References: jsc#PED-1817
Patch-mainline: v5.16-rc1
The 'drd_wq' workqueue_struct has never been used.
It is only destroyed, but never created.
It was introduced in commit 1b9f35adb0ff ("usb: gadget: udc: Add Synopsys
UDC Platform driver")
Remove the corresponding dead code and save some space from the 'udc'
structure.
