From b254a8359ecdc8ec85cd93e055c6bbeee259df1d Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 7 Aug 2024 16:47:24 -0600 Subject: sandbox: Return error code from read/write/seek The existing API for these functions is different from the rest of U-Boot, in that any error code must be obtained from the errno variable on failure. This variable is part of the C library, so accessing it outside of the special 'sandbox' shim-functions is not ideal. Adjust the API to return an error code, to avoid this. Update existing uses to check for any negative value, rather than just -1.
