Subject: staging: fbtft: A bit more information on dev_err.
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e66f30ee1369af24366ce947a29d1362b8cd882c;p=linux.git

staging: fbtft: A bit more information on dev_err.

Adds a bit more information on debug.
The line break was to avoid obfuscating the parameters on the end of a large line.
