[PATCH v2 25/30] ide: Use a single local blk_desc for ide_ident()

Simon Glass sjg at chromium.org
Tue Apr 25 18:54:50 CEST 2023


We only use one member of the ide_dev_desc[] array at a time and it does
not stick around outside ide_probe(). Use a single element instead.

Copy over the missing members of blk_desc at the same, since this was
missing from the previous code.
