For me this hovers extremely close to being a gratuitous renaming
especially with no effort to bridge the gap between old and new names.

On the other hand, no current defconfig enables BACKLIGHT_PM8941_WLED,
it is configured by DT (so modules.conf tricks are unlikely) and any distros
that already have it enables are likely to be aggressive in enabling
drivers (so will probably turn on BACKLIGHT_QCOM_WLED as soon as it
appears).

On that basis I can live with this... but will also listen for any
complaints!
