| | | | | | | | | serio_device_id are not supposed to change at runtime. All functions working with serio_device_id provided by <linux/serio.h> work with const serio_device_id.

* i2c: Remove unneeded xxx_set_drvdata(..., NULL) callsDoug Anderson2013-02-221-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | There is simply no reason to be manually setting the private driver data to NULL in the remove/fail to probe cases. This is just extra cruft code that can be removed. A few notes: * Nothing relies on drvdata being set to NULL. * The __device_release_driver() function eventually calls dev_set_drvdata(dev, NULL) anyway, so there's no need to do it twice. * I verified that there were no cases where xxx_get_drvdata() was being called in these drivers and checking for / relying on the NULL return value. This could be cleaned up kernel-wide but for now just take the baby step and remove from the i2c subsystem.

* i2c-taos-evm: Switch echo off to improve performanceJean Delvare2009-09-181-21/+24
| | | | | | | | When echo is on, we waste time reading back our orders. Switching echo off makes performance much better: SMBus byte data transactions are 47% faster and byte transactions are 24% faster. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c: Consistently reject unsupported transactionsJean Delvare2008-07-141-3/+2
| | | | | | | | | Many PC SMBus host controller drivers don't properly handle the case where they are requested to achieve a transaction they do not support.

* i2c: Convert most new-style drivers to use module aliasingJean Delvare2008-04-291-2/+1
| | | | | | | | | | | | | | Based on earlier work by Jon Smirl and Jochen Friedrich. Update most new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. I've left the video drivers apart (except for SoC camera drivers) as they're a bit more diffcult to deal with, they'll have their own patch later.
