gpio: TODO: add an item to track the conversion to the new value setters 



Add an item tracking the treewide conversion of GPIO drivers to using
the new line value setter callbacks in struct gpio_chip instead of the
old ones that don't allow drivers to signal failures to callers.

conversion. Note that drivers using the generic irqchip framework

cannot be converted yet, but watch this space!



-------------------------------------------------------------------------------



Convert all GPIO chips to using the new, value returning line setters



struct gpio_chip's set() and set_multiple() callbacks are now deprecated. They

return void and thus do not allow drivers to indicate failure to set the line

value back to the caller.



We've now added new variants - set_rv() and set_multiple_rv() that return an

integer. Let's convert all GPIO drivers treewide to use the new callbacks,

remove the old ones and finally rename the new ones back to the old names.
