[PATCH 1/4] target/mips: Fix UHI error values |
Date: |
Sun, 4 Jul 2021 19:07:33 +0200 |
The UHI support was posted *before* [1] the specification was
released, and merged (commit 2c44b19c199) around the same time
[2], using Linux kernel errno values.
Update to use the spec values.

[2] https://lists.gnu.org/archive/html/qemu-devel/2015-06/msg05231.html
Fixes: 2c44b19c199 ("target-mips: convert host to MIPS errno values when
required")
