SubjectRe: [PATCH v3] i2c documentation: rename variable "register" to "reg"
From
Gmail. I just had a look at Documentation/email-clients.txt I thought
that selected unformatted text mode would be enough, but obviously it
wasn't. My bad :-(

Will be more careful next time I send a patch. I will use something else.
