[PATCH] ASoC: sti: sti_uniperif: Remove driver

This driver seems to be in the "only good for attracting bot generated patches" phase of it's life.

It doesn't seem like anyone actually tested the patches that have been applied in the last few years as uni_reader_irq_handler() had a dead lock added to it (it locks the stream, then calls snd_pcm_stop_xrun() which will also lock the stream).

Seems best just to remove it.

Signed-off-by: Daniel Palmer daniel@0x0f.com --- I've never used this driver, don't have the hardware etc. I just noticed that this looks broken when debugging my own driver that uses snd_pcm_stop_xrun() and was looking at other users to see if I was using it wrong and noticed this was the only place that locked the stream before calling snd_pcm_stop_xrun().

There are probably some other bits of the driver that should be removed but I didn't look that hard.

TL;DR; This driver seems broken, seems like nobody uses it. Maybe it should be deleted?
