[PATCH] spi: spi-fsl-spi: Return an error code in fsl_spi_do_one_msg()

[Fabio Estevam]

Since commit c592becbe704127 ("spi: fsl-(e)spi: migrate to generic master
queueing") the function fsl_spi_do_one_msg() is not void anymore, so return
an error code to avoid the following buid warning:

   drivers/spi/spi-fsl-spi.c: In function 'fsl_spi_do_one_msg':
>> drivers/spi/spi-fsl-spi.c:374:4: warning: 'return' with no value, in function returning non-void [-Wreturn-type]
       return;
       ^

Right, missed that. However the code was bogus before, the status =
-EINVAL didn't make sense as the value of variable status isn't used
before the return.
Therefore we can remove the "status = -EINVAL".
Shall I submit a patch or what would be your preferred approach?

Yes, I noticed that as well.

Yes, may be it would be better if you could submit a fix for this as
separate patch, after Mark applies this one, so that we avoid
conflicts.

OK, just submitted the fix as a separate patch.

You mixed the two fixes in one patch. That was not really what I suggested.

Sorry, was a misunderstanding. I re-sent the fix with only removing the
unused variable assignment.
