This is a different patch. Greg gave me his ACK to export usb_cache_string():
https://lore.kernel.org/linux-usb/Y3zyCz5HbGdsxmRT@xxxxxxxxx/
This is a new patch to add an info attribute for the bootloader in
devlink.h. Regardless, I added it to the v5:
https://lore.kernel.org/linux-can/20221130174658.29282-5-mailhol.vincent@xxxxxxxxxx/
@Jakub (and other netdev maintainers): do not pick this, it will go
through linux-can.
Yours sincerely,
