i can make the struct containing only the funcs const, but not the struct that contains the irq/client since i dynamically assign the contents in the probe func
Also I dont see the reason for having the following typedefs:
it made sense in the other drivers i copied this format from, and in an earlier version of the code, but they arent needed anymore, so i'll drop em

i toyed with that a bit, but the generated code was worse because the drvdata helpers are externals -mike -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
