Subject: Re: [PATCH v3 5/5] usb: serial: implement CMSPAR for F81232

Hello.

I had using "scripts/checkpatch.pl -f" to scan original f81232.c.
It reported with "quoted string split across lines", so I merge these
2 strings into 1 in patch 1/5. But it still warning with "line over 80 
character", so I had shorted string with this line.

I will refine my patch set again with more attention.
Thanks for your advice.
