From 15627e847e4356ebdd49e7c3f10a671819995be6 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 1 Jul 2013 00:13:27 +0100 Subject: cassini: Make missing firmware non-fatal The firmware patch for the Saturn PHY fixes a bug, but is not absolutely essential. And its licence is unclear, so it is not included in all distributions. Just log an error message and continue if it is missing or invalid.
