I had to actually read this patch a number of times and then realized I was completely missing the context. Looking at the whole function makes it more obvious what you mean. However I think it'd be much clearer if we just passed the value of bl->props.brightness into the callbacks, that way we can avoid the additional variable.
This won't work I'm afraid, as brightness can be modified prior to being passed to the callback function:
if (bl->props.power != FB_BLANK_UNBLANK) brightness = 0; if (bl->props.fb_blank != FB_BLANK_UNBLANK) brightness = 0; if (pb->notify) brightness = pb->notify(pb->dev, brightness); Alex. -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
