[dpdk-dev] [PATCH 10/15] bus/dpaa: use warn(3) instead of error(3) to improve portability

[Natanael Copa]

Fix build with musl libc by using warn(3) instead of error(3).

This also fixes error message for kzmalloc failures which previously
would have given "Unknown error -1".

Signed-off-by: Natanael Copa <nc...@alpinelinux.org>

Note that err.h is not in POSIX standard either, but is implemented in musl
libc.
