From cda9b352726117779bf2e7a26e19026d42a6cd1f Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Thu, 5 Sep 2019 20:13:46 +0200 Subject: [PATCH] efi_loader: EFI_BLOCK_IO_PROTOCOL.Reset() We cannot do anything in EFI_BLOCK_IO_PROTOCOL.Reset() but this does not justify to return an error. Let EFI_BLOCK_IO_PROTOCOL.Reset() return EFI_SUCCESS.
