Subject: [PATCH 11/17] i2c: pxa: clean up decode_bits()
MIME-Version: 1.0
Content-Disposition: inline
Content-Transfer-Encoding: 8bit
Content-Type: text/plain; charset="utf-8"

Clean up decode_bits() to use pr_cont(), and move the newline into the
function rather than at its two callsites. Avoid printing an
unnecessary space before the newline.
