The Devicetree bindings document does not have to say in the title that
it is a "binding", but instead just describe the hardware.
Drop trailing "bindings" in various forms (also with trailing full
stop):
find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
-not -name 'trivial-devices.yaml' \
-exec sed -i -e 's/^title: \(.*\) [bB]indings\?\.\?$/title: \1/' {} \;

title: STMicroelectonics Multi-Function eXpander (STMFX)
|
|
|
|
description: ST Multi-Function eXpander (STMFX) is a slave controller using I2C for
|
|
communication with the main MCU. Its main features are GPIO expansion,
|
|
main MCU IDD measurement (IDD is the amount of current that flows
|
|
through VDD) and resistive touchscreen controller.
