I2C bus node names are expected to be just "i2c", if there is just one
such node in given example. Replace remaining bad examples with
scripted:
git grep -l '\si2c[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/i2c[0-9] {/i2c {/'

The onsemi MT9M114 is a 1/6-inch 720p (1.26 Mp) CMOS digital image sensor
|
|
with an active pixel-array size of 1296H x 976V. It is programmable through
|
|
an I2C interface and outputs image data over a 8-bit parallel or 1-lane MIPI
|
|
CSI-2 connection.
