From c13a17b73eb0b30070a347111b8c386f4e6a844e Mon Sep 17 00:00:00 2001 From: Oliver O'Halloran Date: Thu, 12 Sep 2019 15:29:44 +1000 Subject: [PATCH] powernv/pci: Allow any write trigger the diag dump Make the dump trigger off any input rather than just '1'. This allows you to write "echo 1> dump_diag_data" and it'll do what you want rather than erroring out pointlessly.
