With the current implementation dev is equivalent to !ret. It is redundant to check both, ret check can be replaced with dev check, and ret check inside the iteration is dead code.

blk: Switch over to using uclass IDs 2022-09-16T15:05:16+00:00 Simon Glass sjg@chromium.org 2022-08-12T01:34:59+00:00 e33a5c6be55e7c012b2851f9bdf90e7f607e72bf We currently have an if_type (interface type) and a uclass id. These are closely related and we don't need to have both. Drop the if_type values and use the uclass ones instead. Maintain the existing, subtle, one-way conversion between UCLASS_USB and UCLASS_MASS_STORAGE for now, and add a comment. Signed-off-by: Simon Glass <sjg@chromium.org>

virtio: call device_probe() in scanning 2022-04-09T19:06:31+00:00 AKASHI Takahiro takahiro.akashi@linaro.org 2022-03-08T11:36:45+00:00 75a9d7504180f01abb3f63ee894476f457c6dbb5 virtio_init() enumerates all the peripherals that are to be materialised with udevices(UCLASS_VIRIO) and creates particular device instances (UCLASS_BlK or whatever else) as children. On the other hand, device_probe() won't be invoked against those resultant udevices unlike other ordinary device drivers do in the driver model. This is particularly inconvenient when we want to add "event notification" callback so that we will be able to automatically create all efi_disk objects in a later patch. With this patch applied, "virtio scan" will work in a similar way to "scsi rescan", "usb start" or others in term of 'probe' semantics. I didn't add this change to virtio_init() itself because this function may be called in board_init_r() (indirectly in board_late_init()) before UEFI subsustem is initialized.
