The PWM backlight still supports passing a enable GPIO line as platform data using the legacy <linux/gpio.h> API.
It turns out that ever board using this mechanism except one is pass .enable_gpio = -1. So we drop all these cargo-culted -1's from all instances of this platform data in the kernel.
The remaning board, Palm TC, is converted to pass a machine descriptior table with the "enable" GPIO instead, and delete the platform data entry for enable_gpio and the code handling it and things should work smoothly with the new API.

Are we waiting on anyone else?
ChangeLog v2->v3:
- Collect Robert's ACK.
ChangeLog v1->v2:
- Located a missing removal of .enable_gpio in the Palm TC board file, pointed out by Daniel.
- Grepped to ascertain there is not a single instance of the string "enable_gpio" in the affected board files.
