[PATCH 3.2 135/147] mct_u232: Fix use of uninitialized pointer in mct_u323_startup()

[Ben Hutchings]

3.2.95-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <b...@decadent.org.uk>

My backport of commit 4e9a0b05257f "USB: mct_u232: add sanity checking in
probe" incorrectly added a dev_err() call using port->dev before 'port' was
initialised.  Use the 'serial' parameter to look up the device instead.
