The script “checkpatch.pl” pointed information out like the
following.
Comparison to NULL could be written ...
Thus fix the affected source code places.

Omit extra messages for a memory allocation failure in these
functions.
This issue was detected by using the Coccinelle software.

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

ioremaped addresses are not linearly mapped so the physical
address can not be figured out via __pa. More generally, there
is no guarantee that backing value of an ioremapped address
is a physical address at all. The value here is only used
for debugging so just drop the call to __pa on the ioremapped
address.

Add X-Gene PMD clock support.
PMD clock is implemented for a single register field.
Output rate = parent_rate * (denominator - scale) / denominator
with
- denominator = bitmask of register field + 1
- scale = values of register field
For example, for bitmask is 0x7, denominator will be 8 and scale
will be computed and programmed accordingly.

In the initial fix for non-zero divider shift value, the parenthesis
was missing after the negate operation. This patch adds the required
parenthesis. Otherwise, lower bits may be cleared unintentionally.

Use the provider based method to get a clock's name so that we
can get rid of the clk member in struct clk_hw one day. Mostly
converted with the following coccinelle script.
@@
struct clk_hw *E;
@@
-__clk_get_name(E->clk)
+clk_hw_get_name(E)

X-Gene clocks implement it's name in the clock private struct.
This is a duplication of the name field. We can delete the field
and rely on the common implementation to retrieve the name.
