linux-next: manual merge of the staging tree with the staging.current tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi Greg,

Today's linux-next merge of the staging tree got a conflict in
drivers/iio/industrialio-buffer.c between commit d66e0452bf6b ("iio: Fix
crash when scan_bytes is computed with active_scan_mask == NUL") from the
staging.current tree and commit 705ee2c98a37 ("iio:buffer: Simplify
iio_buffer_is_active()") from the staging tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
