This can be used as a first approximation on whether i915 will be available. It's safe to use as this is only built when CONFIG_SND_HDA_I915 is selected by CONFIG_I915. It's not completely fool proof, as you can boot with "nomodeset i915.modeset=1" to make i915 load regardless, or use "i915.force_probe=!*" to never load i915, but the common case of booting with nomodeset to disable all GPU drivers this will work as intended. Because of this, we add an extra module parameter, snd_hda_core.gpu_bind that can be used to signal users intent. -1 follows nomodeset, 0 disables binding, 1 forces wait/-EPROBE_DEFER on binding.
