I personally like when commit messages can be read without subject, so
perhaps:
The default_length parameter of alloc_ep_req was not …
But that’s just me.

[PATCH 7/9] usb: gadget: remove useless parameter in alloc_ep_req()
This parameter was not really necessary and gadget drivers would almost always
create an inline function to pass the same value to len and default_len.
So this patch also removes duplicate code from few drivers.
