Subject: [PATCH 0/3] ASoC: wcd9335: Firx some resources leak in the probe and remove function

The first 2 patches are sraightforward and look logical to me.

However, the 3rd one in purely speculative. It is based on the fact that a
comment states that we enable some irqs on some slave ports. That said, it writes
0xFF in some registers.

So, I guess that we should disable these irqs when the driver is removed. That
said, writing 0x00 at the same place looks logical to me.

This cis untested and NOT based on any documentation. Just a blind fix.
Review with care.
You'll be warned :)

    probe function
