[RESEND PATCH 0/7] Export I2C and OF module aliases in missing drivers

[Javier Martinez Canillas]

Hello,

This is a resend of the patches that were not picked from the series
"[PATCH 00/27] Export I2C and OF module aliases in missing drivers" [0]
posted about a month ago.

The patches have no dependencies and can be picked individually by the
relevant maintainer.

I preferred to resend instead of sending a naked ping for each patch
that I got no answer.

Best regards,
Javier

[RESEND PATCH 1/7] i2c: core: Export I2C module alias information in dummy driver

[Javier Martinez Canillas]

The I2C core always reports the MODALIAS uevent as "i2c:<modalias>"
regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: I2C id table or OF match table).

So drivers needs to export the I2C id table and this be built into
the module or udev won't have the necessary information to autoload
the needed driver module when the device is added.

The dummy driver is always loaded when the i2c core inits.

Ok, I wondered if that was the case but I
was not sure so I posted it just in case.

Then this patch should be dropped.

[RESEND PATCH 5/7] extcon: Export OF module alias information in missing drivers

[Javier Martinez Canillas]

The I2C core always reports the MODALIAS uevent as "i2c:<modalias>"
regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: I2C id table or OF match table).

So drivers needs to export the I2C id table and this be built into
the module or udev won't have the necessary information to autoload
the needed driver module when the device is added.

But this means that OF-only drivers needs to have both OF and I2C id
tables that have to be kept in sync and also the dev node compatible
manufacturer prefix is stripped when reporting the MODALIAS. Which can
lead to issues if two vendors use the same I2C device name for example.

To avoid the above, the I2C core behavior may be changed in the future
to not require an SPI device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table even when
is unused now to prevent breaking module loading when the core changes.

So, on the one hand detailed commit messages are nice.  On the other
hand if they wander too far off point it can be hard to sustain
interest and one can glaze over a bit.  All the above really needs to
say is that if we want to use the OF alias table we need to export it.

Ok, I wanted to explain why needs to be added even if currently
is not used. But I'll post a v2 with a shorter commit message.
