You just added a complier warning with this patch:
  CC [M]  drivers/staging/iio/industrialio-buffer.o
drivers/staging/iio/industrialio-buffer.c: In function =E2=80=98iio_sca=
n_mask_query=E2=80=99:
drivers/staging/iio/industrialio-buffer.c:621:8: warning: unused variab=
le =E2=80=98mask=E2=80=99 [-Wunused-variable]

So I didn't apply it.

Care to try again and be more careful in the future?

thanks,
