[ Upstream commit 934b44589da9aa300201a00fe139c5c54f421563 ]

Add MODULE_DEVICE_TABLE(), so modules could be properly autoloaded based on the alias from of_device_id table.

[ Upstream commit 258905cb9a6414be5c9ca4aa20ef855f8dc894d4 ]

We use komeda_crtc_normalize_zpos to normalize zpos of affected planes to their blending zorder in CU. If there's only one slave plane in affected planes and its layer_split property is enabled, order++ for its split layer, so that when calculating the normalized_zpos of master planes, the split layer of the slave plane is included, but the max_slave_zorder does not include the split layer and keep zero because there's only one slave plane in affacted planes, although we actually use two slave layers in this commit.

In most cases, this bug does not result in a commit failure, but assume the following situation: slave_layer 0: zpos = 0, layer split enabled, normalized_zpos = 0;(use slave_layer 2 as its split layer) master_layer 0: zpos = 2, layer_split enabled, normalized_zpos = 2;(use master_layer 2 as its split layer) master_layer 1: zpos = 4, normalized_zpos = 4; master_layer 3: zpos = 5, normalized_zpos = 5; kcrtc_st->max_slave_zorder = 0; When we use master_layer 3 as a input of CU in function komeda_compiz_set_input and check it with function komeda_component_check_input, the parameter idx is equal to normailzed_zpos minus max_slave_zorder, the value of idx is 5 and is euqal to CU's max_active_inputs, so that komeda_component_check_input returns a -EINVAL value.

To fix the bug described above, when calculating the max_slave_zorder with the layer_split enabled, count the split layer in this calculation directly.
