The main goal of this tooling is to collect panic logs, but pstore/ramoops could be set to use other backends, like the console or ftrace ones. With that, save-dumps may end-up collecting these other logs as well, which is out of the scope - hence, fix it to only deal with "dmesg-ramoops" logs. While at it, check the existence of the pstore file; the loop might end-up having a null element, so just mimic the kdump loop and check if it's a valid/existing file. Signed-off-by: Guilherme G.
