Subject: [PATCH 1/2] remoteproc: core: Export the rproc coredump APIs
Date:   Thu, 5 May 2022 23:11:13 +0530

From: Siddharth Gupta <sidgup@codeaurora.org>

The remoteproc coredump APIs are currently only part of the internal
remoteproc header. This prevents the remoteproc platform drivers from
using these APIs when needed. This change moves the rproc_coredump()
and rproc_coredump_cleanup() APIs to the linux header and marks them
as exported symbols.
