NAME
       usb_ep_align_maybe - returns len aligned to ep's maxpacketsize if gadget requires
       quirk_ep_out_aligned_size, otherwise reguens len.

SYNOPSIS
       size_t usb_ep_align_maybe(struct usb_gadget * g, struct usb_ep * ep, size_t len);

ARGUMENTS
       g
           controller to check for quirk

       ep
           the endpoint whose maxpacketsize is used to align len

       len
           buffer size's length to align to ep's maxpacketsize

DESCRIPTION
       This helper is used in case it's required for any reason to check and maybe align buffer's
       size to an ep's maxpacketsize.
