Series efi_loader: more tightly integrate UEFI disks to device model | expand

Commit Message

AKASHI Takahiro Oct. 4, 2021, 3:44 a.m. UTC 
Adding this callback function, efi_disk_create() in block devices's
post_probe hook will allows for automatically creating efi_disk objects
per block device.

This will end up not only eliminating efi_disk_register() called in UEFI
initialization, but also enabling detections of new block devices even
after the initialization.
