Subject: [RFC PATCH] usb: gadget: fsl_qe_udc: fix implicit-fallthrough warnings
Date: Tue, 27 Apr 2021 21:08:55 -0700 [thread overview]
Message-ID: <20210428040855.25907-1-rdunlap@infradead.org> (raw)
Quieten implicit-fallthrough warnings in fsl_qe_udc.c:
../drivers/usb/gadget/udc/fsl_qe_udc.c: In function 'qe_ep_init':

596 | switch (max) {
This basically just documents what is currently being done.
If any of them need to do something else, just say so or
even make the change.
