2014-01-09Documentation: i2c: Remove obsolete exampleHelia Correia
Documentation/i2c/fault-codes illustrates EINVAL error code as follows: "One example would be a driver trying an SMBus Block Write with block size outside the range of 1-32 bytes." However, the actual implementation of i2c subsystem truncates data length to be 32 bytes. Hence this example cannot happen anymore, and since it's obsolete, let's simply remove it from Documentation/i2c/fault-codes.

2008-07-14i2c: Document standard fault codesDavid Brownell
Create Documentation/i2c/fault-codes to help standardize fault/error code usage in the I2C stack. It turns out that returning -1 (-EPERM) for everything was not at all helpful. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
