[PATCH 0/5] i2c: i2c-piix4: set of coding style fixes

[Carlos Palminha]

This patchset fixes several coding style issues.

Carlos Palminha (5):
  i2c: i2c-piix4: coding style fix - '*' adjacent to data name
  i2c: i2c-piix4: coding style fix - assignment in if condition
  i2c: i2c-piix4: coding style fix - long comments blocks
  i2c: i2c-piix4: coding style fix - spaces with open parenthesis
  i2c: i2c-piix4: coding style fix - quoted string split across lines

There's an extra space before "Note:", please remove.

typically, this format would be coalesced into a single line.

Especially when the patch claims to "fix quoted string split across

Except for the two issues which were already pointed out, I'm fine with
these changes, however there is no good reason to split them into 5
separate patches. Fixing the coding style is one goal, it should be all
done with a single patch. So, when you resubmit, please do so as a
single patch.
