I have no reason to believe these boards have any more users and I
haven't tested them for several years. Removing them may simplify
other changes to the various PXA boards people still care about.
The recent conversion of pxa2xx_spi to GPIO descriptors for example
had to update this board despite no one caring or testing.
Great boards that got me started in kernel development, RIP!

We need to set TASK_INTERRUPTIBLE before calling kthread_should_stop().
Otherwise, kthread_stop() might see that the pccardd thread is still
in TASK_RUNNING state and fail to wake it up.
Additionally, we only need to set the state back to TASK_RUNNING if
kthread_should_stop() breaks the loop.

In nonstatic_find_mem_region(), pcmcia_make_resource() is assigned to
res and used in pci_bus_alloc_resource(). There a dereference of res
in pci_bus_alloc_resource(), which could lead to a NULL pointer
dereference on failure of pcmcia_make_resource().
Fix this bug by adding a check of res.
This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.
Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.
Builds with CONFIG_PCCARD_NONSTATIC=y show no new warnings,
and our static analyzer no longer warns about this code.

The driver core ignores the return value of this callback because there
is only little it can do when a device disappears.
This is the final bit of a long lasting cleanup quest where several
buses were converted to also return void from their remove callback.
Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.
With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.

* 'pcmcia-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux:
pcmcia: Switch to using the new API kobj_to_dev()
The driver core ignores the return value of struct device_driver::remove
because there is only little that can be done. To simplify the quest to
make this function return void, let struct sa1111_driver::remove return
void, too. All users already unconditionally return 0, this commit makes
it obvious that returning an error code is a bad idea and ensures future
users behave accordingly.

The driver was introduced in 2.6.11 in the pre-git times with commit
"[PATCH] mips: vR41xx updates". However, even back then, this driver
was not able to be compiled, as a number of udpates had been missing
from this driver: It still provided a "->get_io_map" callback (removed
for v2.5.66) and a "->inquire_socket" callback and used socket_cap_t
(removed for v2.5.72). Moreover, this driver failed to be brought and
be kept up to date; e.g. it still provides '->register_callback',
incompatible with a change committed for v2.6.14 in
commit 7f316b033b ("[PATCH] pcmcia: remove socket register_callback"),
and uses INIT_WORK() with three arguments which was removed in
commit 65f27f3844 ("WorkStruct: Pass the work_struct pointer instead
of context data")

Pull pcmcia updates from Dominik Brodowski:
"Two minor PCMCIA odd fixes: one replacing zero-length arrays with a
flexible-array member, and one making a local function static"
* 'pcmcia-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux:
pcmcia: make pccard_loop_tuple() static
pcmcia: Replace zero-length array with flexible-array
Factor code shared between pci_64 and electra_cf into a ioremap_pbh helper
that follows the normal ioremap semantics, and returns a useful __iomem
pointer. Note that it opencodes __ioremap_at as we know from the callers
the slab is available. Switch pci_64 to also store the result as __iomem
pointer, and unmap the result using iounmap instead of force casting and
using vmalloc APIs.

Remove the loop used to free CardBus resources and replace it with
a yenta_free_res() helper used to release bridge resources explicitly.

pccard_loop_tuple() is only used within drivers/pcmcia/pcmcia_cis.c, so
make that function static.

There are a few space characters I found by chance. I think they are

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

Since snprintf() returns the would-be-output size instead of the
actual output size, the succeeding calls may go beyond the given
buffer limit. Fix it by replacing with scnprintf().
