2006-09-26i2c: __must_check fixes (chip drivers)Jean Delvare
i2c: __must_check fixes (chip drivers) Check for error on sysfs file creation. Delete sysfs files on device removal. The approach taken for the most complex case (pcf8591) is similar to what Mark M. Hoffman proposed for hardware monitoring chip drivers.

2006-07-12[PATCH] pca9539: Honor the force parameterBen Gardner
The pca9539 driver doesn't honor the force parameter; it always does detection. This patch will skip detection if forced. Signed-off-by: Ben Gardner <gardner.ben@gmail.com> Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-01-05[PATCH] I2C: Remove .owner setting from i2c_driver as it's no longer neededGreg Kroah-Hartman
Now that i2c_add_driver() doesn't need the module owner to be set by hand, we can delete it from the drivers. This patch catches all of the drivers that I found in the current tree (if a driver sets the .owner by hand, it's not a problem, just not needed.)

2006-01-05[PATCH] i2c: Drop i2c_driver.{owner,name}, 2 of 11Laurent Riffard
We should use the i2c_driver.driver's .name and .owner fields instead of the i2c_driver's ones. This patch updates the miscellaneaous i2c chip drivers.

2006-01-05[PATCH] i2c: Drop i2c_driver.flags, 2 of 3Jean Delvare
Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we can simply make it the default and drop the flag. If any driver really doesn't want to be notified when i2c adapters are added, that driver can simply omit to set .attach_adapter. This approach is also more robust as it prevents accidental NULL pointer dereferences. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-10-28[PATCH] i2c: kzalloc conversion, other driversDeepak Saxena
Use kzalloc instead of kmalloc+memset in all remaining i2c bus and chip drivers. Signed-off-by: Deepak Saxena <dsaxena@plexity.net> Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-09-05[PATCH] hwmon: hwmon vs i2c, second round (06/11)Jean Delvare
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.

2005-09-05[PATCH] hwmon: hwmon vs i2c, second round (04/11)Jean Delvare
i2c_probe and i2c_detect now do the exact same thing and operate on the same data structure, so we can have everyone call i2c_probe. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-09-05[PATCH] I2C: refactor message in i2c_detach_clientJean Delvare
We could refactor the error message 34 different i2c drivers print if i2c_detach_client() fails in this function itself. Saves quite a few lines of code. Documentation is updated to reflect that change. Note that this patch should be applied after Rudolf Marek's w83792d patches.

2005-09-05[PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (7/9)Jean Delvare
Kill normal_isa in header files, documentation and all chip drivers, as it is no more used. normal_i2c could be renamed to normal, but I decided not to do so at the moment, so as to limit the number of changes. This might be done later as part of the i2c_probe/i2c_detect merge. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-06-21[PATCH] I2C: add new pca9539 driverbgardner@wabtec.com
This is an i2c driver for the Philips PCA9539 (16 bit I/O port). It uses the new i2c-sysfs interfaces. The patch includes documentation. It depends on the patch that renames "i2c-sysfs.h" to "hwmon-sysfs.h" Signed-off-by: Ben Gardner <bgardner@wabtec.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
