Axel Lin 8fb28231a9 ARM: pxa: fix error handling in pxa2xx_drv_pcmcia_probe
If pxa2xx_drv_pcmcia_add_one fails, it will go to err1 error path.
Add a missing clk_put in the error path.

Checking the ret value after the for loop is redundant, it is always false.
Thus remove the redundant checking.

Russell King 025e4ab3db pcmcia: fix socket refcount decrementing on each resume
This fixes a memory-corrupting bug: not only does it cause the warning,
but as a result of dropping the refcount to zero, it causes the
pcmcia_socket0 device structure to be freed while it still has
references, causing slab caches corruption.  A fatal oops quickly
follows this warning - often even just a 'dmesg' following the warning
causes the kernel to oops.

While testing suspend/resume on an ARM device with PCMCIA support, and a
CF card inserted, I found that after five suspend and resumes, the
kernel would complain, and shortly die after with slab corruption.

  WARNING: at include/linux/kref.h:41 kobject_get+0x28/0x50()

As the message doesn't give a clue about which kobject, and the built-in
debugging in drivers/base/power/main.c happens too late, this was added
right before each get_device():

  printk("%s: %p [%s] %u\n", __func__, dev, kobject_name(&dev->kobj), atomic_read(&dev->kobj.kref.refcount));

and on the 3rd s2ram cycle, the following behaviour observed:

Looking at commit 7b24e79882 ("pcmcia: split up central event handler"),
the following change was made to cs.c:

                return 0;
        }
 #endif
-
-       send_event(skt, CS_EVENT_PM_RESUME, CS_EVENT_PRI_LOW);
+       if (!(skt->state & SOCKET_CARDBUS) && (skt->callback))
+               skt->callback->early_resume(skt);
        return 0;
 }

And the corresponding change in ds.c is from:

-static int ds_event(struct pcmcia_socket *skt, event_t event, int priority)
-{
-       struct pcmcia_socket *s = pcmcia_get_socket(skt);
...
-       switch (event) {
...
-       case CS_EVENT_PM_RESUME:
-               if (verify_cis_cache(skt) != 0) {
-                       dev_dbg(&skt->dev, "cis mismatch - different card\n");
-                       /* first, remove the card */
-                       ds_event(skt, CS_EVENT_CARD_REMOVAL, CS_EVENT_PRI_HIGH);
-                       mutex_lock(&s->ops_mutex);
-                       destroy_cis_cache(skt);
-                       kfree(skt->fake_cis);
-                       skt->fake_cis = NULL;
-                       s->functions = 0;
-                       mutex_unlock(&s->ops_mutex);
-                       /* now, add the new card */
-                       ds_event(skt, CS_EVENT_CARD_INSERTION,
-                                CS_EVENT_PRI_LOW);
-               }
-               break;
...
-    }

-    pcmcia_put_socket(s);

-    return 0;
-} /* ds_event */

to:

+static int pcmcia_bus_early_resume(struct pcmcia_socket *skt)
+{
+       if (!verify_cis_cache(skt)) {
+               pcmcia_put_socket(skt);
+               return 0;
+       }

+       dev_dbg(&skt->dev, "cis mismatch - different card\n");

+       /* first, remove the card */
+       pcmcia_bus_remove(skt);
+       mutex_lock(&skt->ops_mutex);
+       destroy_cis_cache(skt);
+       kfree(skt->fake_cis);
+       skt->fake_cis = NULL;
+       skt->functions = 0;
+       mutex_unlock(&skt->ops_mutex);

+       /* now, add the new card */
+       pcmcia_bus_add(skt);
+       return 0;
+}

As can be seen, the original function called pcmcia_get_socket() and
pcmcia_put_socket() around the guts, whereas the replacement code
calls pcmcia_put_socket() only in one path.  This creates an imbalance
in the refcounting.

Testing with pcmcia_put_socket() put removed shows that the bug is gone:

  dpm_suspend: c1a10998 [pcmcia_socket0] 5
  dpm_suspend_noirq: c1a10998 [pcmcia_socket0] 5
  dpm_resume_noirq: c1a10998 [pcmcia_socket0] 5
  dpm_resume: c1a10998 [pcmcia_socket0] 5
  dpm_complete: c1a10998 [pcmcia_socket0] 5

Alan Stern ed283e9f0a USB/PCI/PCMCIA: Clean up new_id and remove_id sysfs attribute routines
This patch (as1514) cleans up some places where new_id and remove_id
sysfs attributes are created and deleted.  Handling both attributes in
a single routine rather than a pair of routines makes the code
smaller.  It also prevents certain kinds of errors, like one we
currently have in the USB subsystem: The removeid attribute is often
created even when newid isn't (because the driver's no_dynamid_id flag
is set).

In the case of the PCMCIA subsystem, the newid attribute is created
but never explicitly deleted.  The patch adds a deletion routine.

Alan Stern cef9bc56e1 Dynamic ID addition doesn't need get_driver()
As part of the removal of get_driver()/put_driver(), this patch
(as1511) changes all the places that add dynamic IDs for drivers.
Since these additions are done by writing to the drivers' sysfs
attribute files, and the attributes are removed when the drivers are
unregistered, there is no reason to take an extra reference to the
drivers.

The one exception is the pci-stub driver, which calls pci_add_dynid()
as part of its registration.  But again, there's no reason to take an
extra reference here, because the driver can't be unloaded while it is
being registered.

It's time to remove the int/unsigned int option.  For this version

Russell King 7a3f8de5a3 ARM: PXA: fix includes in pxa2xx_cm_x2xx PCMCIA driver
The includes in the pxa2xx_cm_x2xx PCMCIA driver are rather random;
the driver doesn't require anything from these headers except the
cpu_is_xxx() macros which come from another include.

The concern is that it's getting these definitions via mach/system.h,
which is supposed to only be included by arch/arm/kernel/process.c.
As this header is scheduled for cleanup (and elimination) keeping
the status quo will cause build errors.  So lets fix properly and
independent of the future work.

- use readl/writel macros so barriers are used where
  necessary.
- register CS3 as GPIO controller with 24 pins
  (16 output only and 8 input only).
- fix PCMCIA driver to access the read-only pins
  rather than the shadow register for status bits.

Arnd Bergmann 97b09da4ee ARM: pxa: use correct __iomem annotations
This tries to clear up the confusion between integers and iomem pointers
in the marvell pxa platform. MMIO addresses are supposed to be __iomem*
values, in order to let the Linux type checking work correctly. This
patch moves the cast to __iomem as far back as possible, to the place
where the MMIO virtual address windows are defined.
