scx200_i2c: Add missing class parameter

2008-11-10T19:18:00Z

commit 4a029abee0f1d69cb0445657d6fa5a38597bd17d upstream The scx200_i2c driver is missing the .class parameter, which means no i2c drivers are willing to probe for devices on the bus and attach to them. Signed-off-by: Len Sorensen Signed-off-by: Jean Delvare Signed-off-by: Greg Kroah-Hartman

i2c-dev: Return correct error code on class_create() failure

2008-10-09T03:22:48Z

In Linus' tree: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commit;h=e74783ec3cb981211689bd2cfd3248f8dc48ec01 We need to convert the error pointer from class_create(), else we'll return the successful return code from register_chrdev() on failure.

i2c: Let users select algorithm drivers manually again

2008-08-20T18:05:09Z

Already in Linus' tree: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=8d24f8dcb7ead491704e274883b2c627062f6235 In kernel 2.6.26, the ability to select I2C algorithm drivers manually was removed, as all in-kernel drivers do that automatically. However there were some complaints that it was a problem for out-of-tree I2C bus drivers. In order to address these complaints, let's allow manual selection of these drivers again, but still hide them by default for better general user experience.

i2c: Fix NULL pointer dereference in i2c_new_probed_device

2008-08-20T18:05:08Z

Already in Linus' tree: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b25b791b13aaa336b56c4f9bd417ff126363f80b Fix a NULL pointer dereference that happened when calling i2c_new_probed_device on one of the addresses for which we use byte reads instead of quick write for detection purpose (that is: 0x30-0x37 and 0x50-0x5f).

I2C: S3C2410: Add MODULE_ALIAS() for s3c2440 device.

2008-07-01T13:30:38Z

Add a MODULE_ALIAS() statement for the i2c-s3c2410 controller to ensure that it can be autoloaded on the S3C2440 systems that we support. Signed-off-by: Ben Dooks

I2C: S3C2410: Fixup error codes returned rom a transfer.

2008-07-01T13:30:37Z

The driver should be returning -ENXIO for transfers that do not pass the initial address byte stage. Note, also small tidyups to the driver comments in the area. Signed-off-by: Ben Dooks

I2C: S3C2410: Check ACK on byte transmission

2008-07-01T13:30:37Z

We should check for the reception of an ACK after transmitting each data byte. The address send has been correctly checking this, but the data write byte state should have also been checking for these failures. As part of the same fix, we remove the ACK checking from the receive path where it should not have been checking for an ACK which our hardware was sending. Signed-off-by: Ben Dooks

i2c/max6875: Really prevent 24RF08 corruption

2008-05-18T18:49:41Z

i2c-core takes care of the possible corruption of 24RF08 chips for quite some times, so device devices no longer need to do it. And they really should not, as applying the prevention twice voids it. I thought that I had fixed all drivers long ago but apparently I had missed that one. Signed-off-by: Jean Delvare Cc: Ben Gardner

i2c-amd756: Fix functionality flags

2008-05-18T18:49:41Z

The i2c-amd756 driver pretends to support SMBus process call transactions but actually does not. Fix it. Signed-off-by: Jean Delvare

i2c: Kill the old driver matching scheme

2008-05-18T18:49:41Z

Remove the old driver_name/type scheme for i2c driver matching. Only the standard aliasing model will be used from now on. Signed-off-by: Jean Delvare
