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.
[Change "! =" to "!=".]

i2c: stub: Add support for banked register ranges 2014-07-17T17:56:15+00:00 Jean Delvare jdelvare@suse.de 2014-07-10T10:56:59+00:00 2408c17fce9236d929b15a975cbd8129de089d62 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.

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.
