Documentation: i2c: 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. [Change "! =" to "!=".] Signed-off-by: Jose Alarcon Roldan <jose.alarcon.roldan@gmail.com> Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Acked-by: Wolfram Sang <wsa@the-dreams.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
