i2c/mips: Fix error return codes from Sibyte i2c bus driver

2010-07-10T07:42:47Z

Sibyte i2c bus driver returns non-descriptive error values. Update to return error values as defined in Documentation/i2c/fault-codes. Signed-off-by: Guenter Roeck Signed-off-by: Jean Delvare

i2c: Fix probability check

2010-07-10T07:42:46Z

The new unified probing function differs from the original code, and the preliminary test whether probing is possible must be updated accordingly. Signed-off-by: Jean Delvare

hwmon: Fix autoloading of fschmd on recent Fujitsu machines

2010-07-09T14:22:51Z

Fujitsu slightly changed the DMI strings in their recent machines, (for example the D2778) and this breaks the automatic loading of the needed fschmd driver. Being more tolerant on string comparison fixes the issue. This closes bug #15634: https://bugzilla.kernel.org/show_bug.cgi?id=15634 Signed-off-by: Jean Delvare Tested-by: Sergey Spiridonov Cc: Hans de Goede

i2c: Remove all i2c_set_clientdata(client, NULL) in drivers

2010-06-03T09:33:58Z

I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

i2c/busses: Move two drivers to embedded section

i2c: Rename i2c_check_addr to i2c_check_addr_busy

2010-06-03T09:33:55Z

Otherwise it's not clear what it is checking. Also move the function to save a forward declaration. Signed-off-by: Jean Delvare

i2c: Document reserved I2C addresses

2010-06-03T09:33:53Z

Move strict I2C address validity check to a single function, and document the reserved I2C addresses there. Signed-off-by: Jean Delvare Cc: Hans Verkuil

i2c: Check for address validity on client registration

2010-06-03T09:33:52Z

Do basic address validity checks when a client is being registered. We already had checks in place for devices which are being detected, but not for devices which are simply instantiated. This is a very basic check. We don't want to do strict checking here because some devices are known to infringe the I2C address constraints (e.g. IR receivers at 7-bit address 0x7a while this value is supposedly reserved for 10-bit addresses.) So we assume the caller knows what it is doing. Signed-off-by: Jean Delvare Cc: Matthieu Castet

i2c: Share the I2C device presence detection code

2010-06-03T09:33:51Z

Use the same I2C device presence detection code for legacy and new device detection functions. This is more consistent and makes the code smaller. Signed-off-by: Jean Delvare Cc: Matthieu Castet
