Sadly the cache is in writeback mode.
Is my understanding correct that the cache itself is fine? It is just the
inability to clear the needs_check flag that is preventing me from using the
device? Or did I miss to run some checks that could reveal a problem / did I
misinterpret the output of cache_check on lv_cache?
