Subject: [PATCH v2 09/28] rust: error: add codes from `errno-base.h`
Date:   Fri,  2 Dec 2022 17:14:40 +0100
Message-Id: <20221202161502.385525-10-ojeda@kernel.org>

From: Viktor Garske <viktor@v-gar.de>

Only a few codes were added so far. With the `declare_err!`
macro in place, add the remaining ones (which is most of them)
from `include/uapi/asm-generic/errno-base.h`.
