Wolfram Sang ea1558ce14 i2c: move drivers from strlcpy to strscpy
Follow the advice of the below link and prefer 'strscpy'. Conversion is
easy because no driver used the return value and has been done with a
simple sed invocation.

Gustavo A. R. Silva df561f6688 treewide: Use fallthrough pseudo-keyword
Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

Wolfram Sang 05d4707d46 i2c: opal: don't check number of messages in the driver
Since commit 1eace8344c ("i2c: add param sanity check to
i2c_transfer()") and b7f6258402 ("i2c: add quirk checks to core"), the
I2C core does this check now. We can remove it here.

Bhumika Goyal ae3923a284 i2c: busses: make i2c_adapter_quirks const
Make these const as they are only stored as a reference in the quirks
field of an i2c_adapter structure, which is const. Done using
Coccinelle.

Suraj Jitindar Singh d0226d315d powerpc/opal: Add inline function to get rc from an ASYNC_COMP opal_msg
An opal_msg of type OPAL_MSG_ASYNC_COMP contains the return code in the
params[1] struct member. However this isn't intuitive or obvious when
reading the code and requires that a user look at the skiboot
documentation or opal-api.h to verify this.

Add an inline function to get the return code from an opal_msg and update
call sites accordingly.

Neelesh Gupta 470834508f i2c: Driver to expose PowerNV platform i2c busses
The patch exposes the available i2c busses on the PowerNV platform
to the kernel and implements the bus driver to support i2c and
smbus commands.
The driver uses the platform device infrastructure to probe the busses
on the platform and registers them with the i2c driver framework.
