It is also apparent that there is an initial open

has the following function:
- Return EBUSY after a configurable amount of time
if a frontend is unavailable due to the other being
in use.
- Only allow opening of a frontend if the kernel thread
of the other has stopped.
This solution was chosen to allow switching between
frontends to work as seamlessly as possible. When both
frontends are actually opened simultaneously then one
will only open, but if quick switching is performed
between one of many then the new open will succeed in
a clean fashion rather than interrupting a kernel

cx88 work from a few weeks ago to add support for this.

supporting functions.

INT#_Clear bit in the Config 1 register. The condition should be that
either of these bits needs changing, but currently it checks the
(self-clearing) Initialization bit instead of INT#_Clear.
Fix the condition and also ensure we never set the Initialization bit.

hwmon: (lm90) Don't spam the kernel log
Degrade the "Unsupported chip" message from info to debug level.
There's nothing wrong with this, so no need to bother the user.
Also make the message slightly more descriptive.

hwmon: (lm90) Rename temperature conversion functions to match usage
The encoding of temperatures varies between chips and modes. So do not
use "temp1" or "temp2" in the names of the conversion functions, but
specify the encoding.

hwmon: (lm90) Convert some macros to static functions
Use static functions instead of the TEMPx_FROM_REG* and TEMPx_TO_REG*
macros. This will ensure type safety and eliminate any side effects
from arguments passed in since the macros referenced 'val' multiple
times. This change should not affect functionality.
