The example code provided with the i2c device interface documentation
won't compile since it uses the reserved word "register" to name a
variable.The compiler fails with this error message:
error: expected identifier or '(' before '=' token
__u8 register = 0x20; /* Device register to access */
^Rename the variable "register" to simply "reg" in the example code.
Another couple of typos has been fixed as well.

Some chips implement banked register ranges. This allows implementing
more registers than the limited 8-bit address space originally allows.
In order to access a register on these chips, you must first select
the proper bank. Add support for this mechanism to the i2c-stub driver
so that such chips can be emulated. All the bank settings are passed
as module parameters.Signed-off-by: Jean Delvare

SMBus block commands are different to I2C block commands since
the returned data is not normally accessible with byte or word
commands on other command offsets. Add linked list of 'block'
commands to support those commands.Access mechanism is quite simple: Block commands must be written
before they can be read. Subsequent writes can be partial. Block
read commands always return the number of bytes associated with
the longest previous write.Signed-off-by: Guenter Roeck

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.Signed-off-by: Helia Correia
