Khadija,

I've applied your patch and it fails to compile with the warnings
that LKP reports.

If you are doing: $ make drivers/staging/axis-fifo/

and it is saying 'nothing to be done...'

You either have not changed anything since the last compile, or you
do not have the module configured.

I suspect it has never compiled for you and you need to look at
the direction in the tutorial for 'Recompiling the driver' section
and learn how to use make menuconfig.

This driver has a couple of dependencies described in the Kconfig
file. You will not even see the 'XIL_AXIS_FIFO' option until you
turn on 'OF' and HAS_'IOMEM'.

See the drivers/staging/axis-fifo/Kconfig

Please confirm that you have compiled the driver before chasing
after the build env that lkp reports.

Thanks,
Alison
