Subject: patch "usb: gadget: select CONFIG_CRC32" added to usb-linus
Date: Mon, 04 Jan 2021 16:54:54 +0100 [thread overview]
Message-ID: <1609775694136137@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
usb: gadget: select CONFIG_CRC32
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: usb: gadget: select CONFIG_CRC32
Without crc32 support, this driver fails to link:
arm-linux-gnueabi-ld: drivers/usb/gadget/function/f_eem.o: in function `eem_unwrap':
f_eem.c:(.text+0x11cc): undefined reference to `crc32_le'
arm-linux-gnueabi-ld: drivers/usb/gadget/function/f_ncm.o:f_ncm.c:(.text+0x1e40):
more undefined references to `crc32_le' follow
Fixes: 6d3865f9d41f ("usb: gadget: NCM: Add transmit multi-frame.")
