Use ida_alloc_xxx()/ida_free() instead of ida_simple_get()/ida_simple_remove(). The latter is deprecated and more verbose. Signed-off-by:

backlight_properties.fb_blank is deprecated. The states it represents are handled by other properties; but instead of accessing those properties directly, drivers should use the helpers provided by backlight.h. Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes.

This started with work on the removal of backlight_properties' deprecated fb_blank field, much of which can be taken care of by using helper functions provided by backlight.h instead of directly accessing fields in backlight_properties. This patch series doesn't involve fb_blank, but it still seems useful to use helper functions where appropriate. Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes.

Instead of setting the power state by manually updating fields in struct backlight_properties, use backlight_enable() and backlight_disable(). These also call backlight_update_status() so the separate call is no longer needed. Signed-off-by:

Instead of manually checking the power state in struct backlight_properties, use backlight_is_blank(). While we're at it, drop .fb_blank from the initialisation function; it is deprecated, and this helps make progress towards enabling its removal. This change makes no functional difference since FB_BLANK_UNBLANK is the default value. Signed-off-by:

Drive-by cleanup, we don't need to validate the port references here as we already previously went through the effort of refactoring things such that we're guaranteed to be able to access ->mstb and ->port safely from drm_dp_check_and_send_link_address(), since the only two places in the codebase that drop an MST reference in such a way that it would remove it from the topology are both protected under probe_lock. Thanks for that, past Lyude! Signed-off-by:

This implements the callback added by the patch ("drm/dp: Add wait_hpd_asserted() callback to struct drm_dp_aux"). With this change and all the two "DP AUX Endpoint" drivers changed to use wait_hpd_asserted(), we no longer need to have an long delay in the AUX transfer function. It's up to the panel code to make sure that the panel is powered now. If someone tried to call the aux transfer function without making sure the panel is powered we'll just get a normal transfer failure. We'll still keep the wait for HPD in the pre_enable() function. Though it's probably not actually needed there, this driver is used in the old mode (pre-DP AUX Endpoints) and it may be important for those cases. If nothing else, it shouldn't cause any big problems. NOTE: When handling the timeout for HPD we start the timer _after_ we've runtime resumed the device. This is definitely important for the panel on my homestar which comes up 170 ms after we start timing (the panel specifies 200 ms max). It's a little unclear how much of this extra time is due to some internal state machine in the parade firmware vs. debouncing but it seems to work for the two test cases I have to do it this way.
