Subject: Re: [PATCH v4 8/9] i2c: npcm: Remove own slave addresses 2:10

Hi Andy:

I would like to have your comments about the "Fancy indentation"
because I'm not sure if I get the point.

I remove extra empty lines and reformat the commit message.

Please see the details below.

Thank you.

I modify the commit message as following:

NPCM can support up to 10 own slave addresses. In practice, only one
address is actually being used. In order to access addresses 2 and above,
need to switch register banks. The switch needs spinlock.
To avoid using spinlock for this useless feature removed support of SA >=
2. Also fix returned slave event enum.

Remove some comment since the bank selection is not required. The bank
selection is not required since the supported slave addresses are reduced.
