Since the addition of the non-CODEC control adds card controls like the
DAPM pin switch have been broken as they are expecting the private data
for the control to be the CODEC but it's now the card. Fix that for the
pin switches, an audit of other drivers is required.

Currently when DAPM widgets are power sequenced the stream_event()
completion callback is only called for the stream_event originator
DAPM context. Other components in the card may also be interested so
make sure they are also notified of any widget power events.

The main role of the WM9081 is as a class D speaker amplifier so there
is no concern about pops. There are also very few registers and a fast

The enable of the single ended line outputs on wm_hubs devices performs
better if the output is enabled prior to starting VMID. Since inactive
outputs are held at VMID anyway there is little cost to doing this for
unused outputs. Add callbacks into wm_hubs and keep track of which outputs
are really active so we can disable them once we're active.

The new ASoC dynamic PCM core needs to create PCMs and substreams that are
for use by internal ASoC drivers only and not visible to userspace for
direct IO. These new PCMs are similar to regular PCMs expect they have no
device nodes or procfs entries. The ASoC component drivers use them in exactly
the same way as regular PCMs for PCM and DAI operations.
The intention is that a dynamic PCM based driver will register both regular
PCMs and internal PCMs. The regular PCMs will be used for all IO with userspace
however the internal PCMs will be used by the driver to route digital audio
through numerous back end DAI links (with potentially a DSP providing different
hw_params, DAI formats based on the regular front end PCM params) to devices
like CODECs, MODEMs, Bluetooth, FM, DMICs, etc
This patch adds a new snd_pcm_new_internal() API call to create the internal PCM
without device nodes or procfs. It also adds adds a new internal flag to snd_pcm.

SPI bug fixes for v3.3-rc2
Minor SPI device driver changes. A rename of the pch_spi_pcidev symbol
that merely eliminates a modpost warning, and a Kconfig change to allow
the Samsung spi driver to build on EXYNOS.
* tag 'spi-for-linus' of git://git.secretlab.ca/git/linux-2.6:
spi-topcliff-pch: rename pch_spi_pcidev to pch_spi_pcidev_driver
spi: Add spi-s3c64xx driver dependency on ARCH_EXYNOS4
Five fixes
* branch 'akpm':
pcmcia: fix socket refcount decrementing on each resume
mm: fix UP THP spin_is_locked BUGs
drivers/leds/leds-lm3530.c: fix setting pltfm->als_vmax
mm: compaction: check for overlapping nodes during isolation for migration
nilfs2: avoid overflowing segment numbers in nilfs_ioctl_clean_segments()
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.

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 */

+ 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:

In current code, pltfm->als_vmin is set to LM3530_ALS_WINDOW_mV and
pltfm->als_vmax is 0. This does not make sense. I think what we want
here is setting pltfm->als_vmax to LM3530_ALS_WINDOW_mV.
Both als_vmin and als_vmax local variables will be set to
pltfm->als_vmin and pltfm->als_vmax by a few lines latter. Thus also
remove a redundant assignment for als_vmin and als_vmax in this patch.
