mtd: Consistently define pci_device_ids 2026-05-27T09:11:04+00:00 Uwe Kleine-König (The Capable Hub) u.kleine-koenig@baylibre.com 2026-05-22T17:32:34+00:00 ad1bcd3469bdb2c5d75c8c29f1944b3ac0f12f92 Initializing a pci_device_id using plain list expressions is hard to understand for a human who isn't into the Linux PCI subsystem. So for each initializer use one of the PCI_DEVICE macros for .vendor, .device, .subvendor and .subdevice and named initializers for the remaining assignments. This makes it easier to parse and also more robust against chagnes to the struct definition. Also drop useless zeros and commas. The mentioned robustness is relevant for a planned change to struct pci_device_id that replaces .driver_data by an anonymous union. This change doesn't introduce changes to the compiled pci_device_id array. Tested on x86 and arm64.
