Subject: i2c: reword i2c_algorithm according to newest specification
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=a93c2e5fe766825d6264823fd1dca9aae747cf5d;p=users%2Fjedix%2Flinux-maple.git

i2c: reword i2c_algorithm according to newest specification

Start changing the wording of the I2C main header wrt. the newest I2C
v7 and SMBus 3.2 specifications and replace "master/slave" with more
appropriate terms. The first step renames the members of struct
i2c_algorithm. Once all in-tree users are converted, the anonymous union
will go away again. All this work will also pave the way for finally
seperating the monolithic header into more fine-grained headers like
"i2c/clients.h" etc.
