As noted by Akinobu Mita in patch b1fceac2b9e04d278316b2faddf276015fc06e3b,
alloc_bootmem and related functions never return NULL and always return a
zeroed region of memory. Thus a NULL test or memset after calls to these
functions is unnecessary.
This was fixed using the following semantic patch.

This patch is as small a change as possible to the KS8695 GPIO layer
to use GPIOLIB to allow the generic GPIO expanders and the like to
be compiled.
As a side-effect, we also remove __init_or_module from several
functions which could be called by drivers such as i2c-gpio which
could plausibly be compiled into a non-modular kernel.

The KS8695 device.c provides registration functionality for the
KS8695's various devices such as watchdog timers and ethernet
devices. Rather than predicating those on the config options for the
drivers, always register the platform devices so that a later built
module can hook on. Also, the ethernet used to register virtual
addresses in the platform data. This is wrong and so this patch
changes them to physical addresses and also passes in the
appropriate physical region for the PHY or Switch as appropriate.

dma_supported() is supposed to indicate whether the system can support
the DMA mask it was passed, which depends on the maximal address which
can be returned for DMA allocations. If the mask is smaller than that,
we are unable to guarantee that the driver can reliably obtain suitable
memory.

On newer versions of the RD88F6281 board, the WAN port is connected to
its own ethernet port on the CPU, via a separate PHY, whereas on older
versions of the board, it is connected to one of the PHYs in the
ethernet switch. In the RD8F6281 setup code, detect which version of
the board we are running on, and instantiate the ethernet ports and
switch driver accordingly.

Based on similar code from the tsx09 series of machines, just rips the MAC
address out of flash and stuffs it into the NIC. Tested on a DNS323 rev B1.
It's possible (though unlikely) that an A1 will have the MAC in a different
location in flash.

The GPTIMER TLDR register does not need to be written if the GPTIMER
is not in autoreload mode. This is the usual case for dynamic tick-enabled
kernels.
Simulation data indicate that skipping the read that occurs as part of
the write should save at least 300-320 ns for each GPTIMER1 timer
reprogram. (This assumes L4-Wakeup is at 19MHz and GPTIMER write
posting is enabled.) Skipping the write itself probably won't have
much impact since it should be posted on the OCP interconnect.
Tested on 2430SDP and 3430SDP.

More conversion to the standard GPIO interfaces: stop using
omap_set_gpio_direction() entirely, and switch over to the
gpio_direction_output() call.
Note that because gpio_direction_output() includes the initial
value, this change isn't quite transparent.
- For the call sites which defined an initial value either
before or after setting the direction, that value was used.
When that value was previously assigned afterwards, this
could eliminate a brief output glitch ... and possibly
change behavior. In a few cases (LCDs) several values
were assigned together ... those were re-arranged to match
the explicit sequence provided.
- Some call sites didn't define such a value; so I chose an
initial "off/reset" value that seemed to default to "off".
In short, files touched by this patch might notice some small
changes in startup behavior (with trivial fixes).

This patch replaces some legacy OMAP GPIO calls with the "new" (not
really, any more!) calls that work on most platforms.
The calls addressed by this patch are the simple ones to get and set
values ... for code that's in mainline, including the implementations
of those calls.
Except for the declarations and definitions of those calls, all of
these changes were performed by a simple SED script. Plus, a few
"if() set() else set()" branches were merged by hand.
