Subject: [lm-sensors] [PATCH] sensors-detect: restrict Super I/O probing to x86
Date: Sun, 09 Aug 2015 10:00:48 +0000 [thread overview]
Message-ID: <20150809100048.GA8036@aurel32.net> (raw)
The current sensors-detect avoid Super I/O chips probing on
PowerPC machines. However I have also been reported that this code
can also crash ARM machines. I therefore believe the probing should
be done only on x86 machines. The patch below changes that.
