Takashi Iwai ba8bb7dce1 ALSA: cs4231: Fix -Wformat-truncation warning for longname string
The filling of card->longname can be gracefully truncated, as it's
only informative.  Use scnprintf() and suppress the superfluous
compile warning with -Wformat-truncation.

Takashi Iwai 2a47145259 ALSA: sscape: Fix -Wformat-truncation warning
The warning with -Wformat-truncation at sscape_upload_microcode() is
false-positive; the version number can be only a single digit, hence
fitting with the given string size.

For suppressing the warning, replace snprintf() with scnprintf().
As stated in the above, truncation doesn't matter.

Takashi Iwai 4cbc7d9cdf ALSA: sb: Fix wrong argument in commented code
While rewriting the code from sockptr_t to iov_iter during the
development, I forgot to replace one place in emu8000-pcm code.  As
it's in the disabled area (with ifdef), it's never built and
overlooked.  Replace with the proper argument NULL.

Takashi Iwai 9d0fdc602d ALSA: emu8000: Convert to generic PCM copy ops
This patch converts the SB Emu8000 driver code to use the new unified
PCM copy callback.  The conversion is a bit complicated because of
many open code in emu8000_pcm.c.  GET_VAL() and LOOP_WRITE() macros
were rewritten / simplified with copy_from_iter().  As
copy_from_iter() updates the internal offset value, we can drop the
corresponding part, too.

Takashi Iwai 192c4cccd0 ALSA: control: Take controls_rwsem lock in snd_ctl_remove()
So far, snd_ctl_remove() requires its caller to take
card->controls_rwsem manually before the call for avoiding possible
races.  However, many callers don't care and miss the locking.

Basically it's cumbersome and error-prone to enforce it to each
caller.  Moreover, card->controls_rwsem is a field that should be used
only by internal or proper helpers, and it's not to be touched at
random external places.

This patch is an attempt to make those calls more consistent: now
snd_ctl_remove() takes the card->controls_rwsem internally, just like
other API functions for kctls.  Since a few callers already take the
controls_rwsem locks, the patch removes those locks at the same time,
too.

Arnd Bergmann f95a387cde m68k: coldfire: drop ISA_DMA_API support
After a build regression report, I took a look at possible users of
CONFIG_ISA_DMA_API on m68k and found none, which Greg confirmed. The
CONFIG_GENERIC_ISA_DMA option in turn is only needed to implement
ISA_DMA_API, and is clearly not used on the platforms with ISA support.

The CONFIG_ISA support for AMIGA_PCMCIA is probably also unneeded,
but this is less clear. Unlike other PCMCIA implementations, this one
does not use the drivers/pcmcia subsystem at all and just supports
the "apne" network driver. When it was first added, one could use
ISA drivers on it as well, but this probably broke at some point.

With no reason to keep this, let's just drop the corresponding files
and prevent the remaining ISA drivers that use this from getting built.

The remaining definitions in asm/dma.h are used for PCI support.

Takashi Iwai a34ae6c066 ALSA: wavefront: Proper check of get_user() error
The antient ISA wavefront driver reads its sample patch data (uploaded
over an ioctl) via __get_user() with no good reason; likely just for
some performance optimizations in the past.  Let's change this to the
standard get_user() and the error check for handling the fault case
properly.

The previous cleanup with devres may lead to the incorrect release
orders at the probe error handling due to the devres's nature.  Until
we register the card, snd_card_free() has to be called at first for
releasing the stuff properly when the driver tries to manage and
release the stuff via card->private_free().

This patch fixes it by calling snd_card_free() on the error from the
probe callback using a new helper function.

Xiaomeng Tong 0112f822f8 ALSA: cs4236: fix an incorrect NULL check on list iterator
The bug is here:
	err = snd_card_cs423x_pnp(dev, card->private_data, pdev, cdev);

The list iterator value 'cdev' will *always* be set and non-NULL
by list_for_each_entry(), so it is incorrect to assume that the
iterator value will be NULL if the list is empty or no element
is found.

To fix the bug, use a new variable 'iter' as the list iterator,
while use the original variable 'cdev' as a dedicated pointer
to point to the found element. And snd_card_cs423x_pnp() itself
has NULL check for cdev.

Takashi Iwai ca4c5b334f ALSA: msnd: Use proper mmap method
The old ISA MSND driver basically maps the iomem as the DMA buffer.
For this type of buffer, we have already the standard mmap helper,
snd_pcm_lib_mmap_iomem().  Correct the PCM info, set the DMA address
and use the standard helper for handling the mmap on all architectures
properly.

Takashi Iwai df8bcf36be ALSA: es1688: Avoid devres management for es1688 object creation
The recent refactoring of es1688 object creation with the use of
devres caused a problem with the non-PnP probe of GUS driver, as it
tries to probe multiple times with different parameters  That is, this
object needs the immediate resource release and the devres doesn't fit
for it.

This patch reverts partially the commit for restoring the classic
resource management for es1688 object.

Takashi Iwai f976e8a941 ALSA: sc6000: Use explicit cast for __iomem pointer
The recent optimization to store an iomem pointer in card's
private_data field caused sparse warnings.  Although they are
practically harmless, add the explicit cast for avoiding the spurious
warnings.

Takashi Iwai 9b7843d1e1 ALSA: sc6000: Assign vport directly on card's private_data
sc6000 driver tries to allocate an extra pointer for keeping the vport
address and point it over card->private_data.  But, this indirect
access is utterly superfluous, and we can keep the vport address
directly in card->private_data instead.  This will simply the code and
avoid confusion.

Static analysis is warning that the sizeof being used is should be
of *vport and not vport. Although these are the same size it is not
a portable assumption to assume this is true for all cases.  Fix this
by using sizeof(*vport).
