drm/i915: Pass port to intel_panel_bl_funcs.get()
In the next commit where we split PWM related backlight functions from
higher-level backlight functions, we'll want to be able to retrieve the
backlight level for the current display panel from the
intel_panel_bl_funcs->setup() function using pwm_funcs->get(). Since
intel_panel_bl_funcs->setup() is called before we've fully read in the
current hardware state into our atomic state, we can't grab atomic
modesetting locks safely anyway in intel_panel_bl_funcs->setup(), and some
PWM backlight functions (vlv_get_backlight() in particular) require knowing
the currently used pipe we need to be able to discern the current display
pipe through other means. Luckily, we're already passing the current
display pipe to intel_panel_bl_funcs->setup() so all we have to do in order
to achieve this is pass down that parameter to intel_panel_bl_funcs->get().
So, fix this by accepting an additional pipe parameter in
intel_panel_bl_funcs->get(), and leave figuring out the current display
pipe up to the caller.
