Subject: lm90 driver no longer working on PCs in 3.13
Date: Sun, 26 Jan 2014 11:28:16 -0800 [thread overview]
Message-ID: <52E561D0.4040308@roeck-us.net> (raw)
Hi,
the lm90 driver is no longer working on PCs with the 3.13 kernel ... or at least not without
special configuration.
This is what I get if I try to instantiate a device on it (max6695):
i2c 1-0018: Driver lm90 requests probe deferral
i2c i2c-1: new_device: Instantiated device max6695 at 0x18
The regulator core always returns -EPROBE_DEFER if the platform does not support devicetree
and if the regulator it is looking for does not exist. Since the driver now requires a mandatory
regulator (commit 3e0f964f2ad - hwmon: (lm90) Add power control), and the regulator it requests
does not exist on a PC, the result is not really surprising. I thought the regulator core would
realize that it has to return a dummy regulator, but apparently that is not the case, or I don't
know how to configure it.
Any idea what I might need to do to get it working ?
Thanks,
Guenter
