Hi Hector,

Thank you for the patch.

This line doesn't exceed the 80 columns limit, no need to split it.

while do you split the line here and not right before the 80 columns limit ?

This isn't the preferred comment style for the kernel, see 
http://lkml.iu.edu/hypermail/linux/kernel/1607.1/00627.html. The problem 
doesn't predate your patch, but while at it you might want to fix it through 
the driver.

How does adding a blank line here fix a coding style issue ?
