[PATCH] i2c: kill an unused i2c_adapter struct member

2005-09-17T18:50:02+00:00

Kill an unused member of the i2c_adapter structure.  This additionally
fixes a potential bug, because  doesn't include
, so different files including  could see a
different definition of the i2c_adapter structure, depending on them
including  (or other header files themselves including
) before , or not.

Credits go to J�rn Engel for pointing me to the problem.

[PATCH] I2C: Drop the I2C_ACK_TEST ioctl

2005-09-05T16:26:56+00:00

Drop the I2C_ACK_TEST ioctl, which was commented out. It never really
existed (not after 1999 anyway), and there is no such thing as a ack
test on I2C/SMBus anyway.

[PATCH] I2C: Drop I2C_DEVNAME and i2c_clientname

2005-09-05T16:14:35+00:00

I2C_DEVNAME and i2c_clientname were introduced in 2.5.68 [1] to help
media/video driver authors who wanted their code to be compatible with
both Linux 2.4 and 2.6. The cause of the incompatibility has gone since
[2], so I think we can get rid of them, as they tend to make the code
harder to read and longer to preprocess/compile for no more benefit.

I'd hope nobody seriously attempts to keep media/video driver compatible
across Linux trees anymore, BTW.

[PATCH] I2C: Outdated i2c_adapter comment

2005-09-05T16:14:33+00:00

Delete an outdated comment about i2c_algorithm.id being computed
from algo->id.

[PATCH] I2C: Kill i2c_algorithm.id (4/7)

2005-09-05T16:14:29+00:00

There are no more users of i2c_algorithm.id, so we can finally drop
this structure member.

[PATCH] I2C: Kill i2c_algorithm.name (1/7)

2005-09-05T16:14:27+00:00

The name member of the i2c_algorithm is never used, although all
drivers conscientiously fill it. We can drop it completely, this
structure doesn't need to have a name.

[PATCH] hwmon: hwmon vs i2c, second round (06/11)

2005-09-05T16:14:21+00:00

The only thing left in i2c-sensor.h are module parameter definition
macros. It's only an extension of what i2c.h offers, and this extension
is not sensors-specific. As a matter of fact, a few non-sensors drivers
use them. So we better merge them in i2c.h, and get rid of i2c-sensor.h
altogether.

[PATCH] hwmon: hwmon vs i2c, second round (01/11)

2005-09-05T16:14:18+00:00

Add support for kind-forced addresses to i2c_probe, like i2c_detect
has for (essentially) hardware monitoring drivers.

Note that this change will slightly increase the size of the drivers
using I2C_CLIENT_INSMOD, with no immediate benefit. This is a
requirement if we want to merge i2c_probe and i2c_detect though, and
seems a reasonable price to pay in comparison with the previous
cleanups which saved much more than that (such as the i2c-isa cleanup
or the i2c address ranges removal.)

[PATCH] I2C: inline i2c_adapter_id

2005-09-05T16:14:15+00:00

We could inline i2c_adapter_id, as it is really, really short. Doing
so saves a few bytes both in i2c-core and in the drivers using this
function.
