[PATCH] crypto: asymmetric_keys - Remove unused key_being_used_for[]

From: linux
Date: Sun Jan 12 2025 - 11:31:21 EST


From: "Dr. David Alan Gilbert" <linux@xxxxxxxxxxx>

key_being_used_for[] is an unused array of textual names for
the elements of the enum key_being_used_for. It was added in 2015 by
commit 99db44350672 ("PKCS#7: Appropriately restrict authenticated
attributes and content type")

Remove it.
