when it starts and restore the values, when it exits.

DDR4 SPD is quite similar to DDR3 SPD. Key difference for detection is
the DDR type, which is 0x0c or 12 for DDR4.

From Brendan Heading:
You may be aware of the musl C-library implementation, which tries to
be strictly standards compliant, avoids non-standard extensions, etc.
Some distributions have adopted it as their standard C library, in
others (such as buildroot) it is a configuration alternative.
Vanilla lm-sensors does not compile under musl, due to the following
excerpt which appears in four different places. The code is checking
that the glibc version is greater than 2.0.
#if defined(__GLIBC__) && __GLIBC__ == 2 && __GLIBC_MINOR__ >= 0
#include <sys/io.h>
#else
#include <asm/io.h>
#endif
This fails under musl does not define __GLIBC__ (in fact, by design,
it doesn't provide any way to identify itself at all) - which causes
it to try to include <asm/io.h> rather than <sys/io.h>.
It's a long time since glibc 2.0.1 was released - 1997. Accordingly,
it seems to make little sense at this stage to try to retain
compatibility with very old libcs - so maybe it should be removed
entirely.
Construct "wait $!" causes bash to remember the exit status of the
children. This consumes memory. We don't need the status code and we
are only waiting for a single child, so we can simply use "wait". This
will reduce the memory usage.
This partly fixes ticket #2391.

The actual leak is in bash 4.3 and should be fixed there.
We already skip EDID addresses (0x50-0x57) by default on graphics card
I2C/DDC buses. Also skip 0x37 (DDC/CI) and 0x4f which was recently
reported as corrupting a laptop's display when probed.
This closes ticket #2392.
http://www.lm-sensors.org/ticket/2392
On recent kernels, the i2c bus may not be an immediate child of the
graphics device, instead there can be a drm class device in between.
Treat all drm class devices as graphics devices so that probing the
i2c bus is disabled by default as intended.
Also strengthen chip detection for other TMP4xx chips,
and update driver support status for TMP431 and TMP432.
Write new function for various TMP4xx chips and separate
from lm90 detection.
Show that nct6775 driver supports NCT6792D.
Show that NCT6102D/6104D/6106D are supported by nct6775 driver.
NCT5573D is compatible to NCT6776F and has the same chip ID.
The bug was introduced when I added support for multiple fans
controlled by the same PWM output, in r6000. lm-sensors versions
affected: 3.3.2 to 3.3.5.
