The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

The call to platform_get_resource(pdev, IORESOURCE_MEM, 0) is moved coser
to the call to devm_request_and_ioremap, which is th first use of the
result of platform_get_resource.

This does not use devm_request_irq to ensure that free_irq is executed
before its idev argument is freed.

The per driver iio_chan_spec arrays are usually shared between multiple device
instances. So a single device instance may not modify the iio_chan_spec array
since this would also affect the other device instances. To make this restriction
explicit mark the per driver iio_chan_spec arrays as const.

Conversion was done automatically using the following coccinelle semantic patch:

// <smpl>
@disable optional_qualifier@
identifier channels;

static
+const
struct iio_chan_spec channels[] = ...;

If we end up returning -EINVAL from the function we will leak the

Fix the leak by properly freeing the memory again before we return.

This patchset provides page mapping via the page table.
On some archs, most notably ARM, this method has been
demonstrated to be faster than copying.

The logic controlling the method selection (copy vs page table)
is controlled by the definition of USE_PGTABLE_MAPPING which
is/can be defined for any arch that performs better with page
table mapping.

it is the first of a pair of pages needing to be mapped.

The current value for the maximum receive buffer size is 30720, which is
too large. For long-running systems, memory fragmentation may make it
difficult to obtain the buffers of O(2) needed for aggregation. Buffers
of O(3) are even worse, particularly when not needed. The new size is set
to 9100, which will allow aggregation.
