Subject: [PATCH v2] i2c documentation: rename variable "register" to "reg"
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.
