Just using designated initializers is not enough for dvb-usb, as the big issue there is really the fact that the dvb-usb struct needs to point to the entries inside the USB ID table. Also, your patch touches only two of the several dvb-usb drivers. So, I ended taking some time and writing a series: https://lore.kernel.org/linux-media/cover.1648499509.git.mchehab@xxxxxxxxxx/T/#t Giving you credits for suggesting it at the dibusb-* patches. > It was suggested to make the arrays const, but that didn't compile. Yeah, the struct that points to it is not marked as const, as there are a couple of drivers that actually change some things there. As I said, the real fix would be to just migrate the drivers from the legacy dvb-usb core to the newer dvb-usb-v2. But, at least with the newer series, the risk of pointing to the wrong entry is reduced.
