If you look very close at the added lines, you see that the
continued line (the opening quote of the string) does not align
with the start of the parameter list of the previous line (the
'dev' word).  And it appears to not be a false positive due to
the use of TABs, as in the above quote the "ret = " starts at
position 8 as well.

But as mentioned, it's a nit.  And if nobody else objects neither
will I.  It's just too minor, and does not affect operation.

Sorry for the slow response. This is likely fine, since the SPI
controller has a dedicated interrupt.
