commit 74457c40f97a98142bb13153395d304ad3c85cdd upstream
With introduction of rproc_alloc_registered_carveouts() which delays carveout allocation just before the start of the remote processor, rproc_da_to_va() could be called before all carveouts are allocated. This patch adds a check in rproc_da_to_va() to return NULL if carveout is not allocated.
Fixes: d7c51706d095 ("remoteproc: add alloc ops in rproc_mem_entry struct")
This commit only shows up in 4.20, not 4.19, so why is this patch relevant for 4.19?
Your scripts are better than mine...
thanks,
