Subject: i2c: Let i2c-core.h include <linux/i2c.h>
X-Git-Tag: v7.2-rc2~18^2~9

i2c: Let i2c-core.h include <linux/i2c.h>

The subsystem private header i2c-core.h uses several symbols defined in
<linux/i2c.h>, e.g. struct i2c_board_info and i2c_lock_bus()). This
doesn't pose a problem in practise because all files including
"i2c-core.h" also include <linux/i2c.h>.

To make this more robust add an include statement for <linux/i2c.h>
making the header self-contained.
