The snd_pcm name may overflow the card->longname total size:

sound/isa/cs423x/cs4231.c: In function 'snd_cs4231_probe':
sound/isa/cs423x/cs4231.c:115:26: error: ' at 0x' directive writing 6 bytes into a region of size between 1 and 80 [-Werror=format-overflow=] 0x%lx, irq %d, dma %d",
  sprintf(card->longname, "%s at 0x%lx, irq %d, dma %d",
                          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This changes the driver to use snprintf() so we truncate the string
instead of overflowing into the next field if that happens.

I decided to split out the second format string for the extra
DMA channel to keep the code simpler.

The compiler sees that the format string might overflow for the longname:

sound/isa/als100.c: In function 'snd_als100_pnp_detect':
sound/isa/als100.c:225:27: error: ', dma ' directive writing 6 bytes into a region of size between 0 and 64 [-Werror=format-overflow=]
   sprintf(card->longname, "%s, %s at 0x%lx, irq %d, dma %d",
                           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
sound/isa/als100.c:225:3: note: 'sprintf' output between 24 and 113 bytes into a destination of size 80
   sprintf(card->longname, "%s, %s at 0x%lx, irq %d, dma %d",

Open-coding "shortname" here gets us below the limit, and using
snprintf() is a good idea too.

The commit b56fa687 ("ALSA: fm801: detect FM-only card earlier")
rearranged initialization calls, i.e. it makes snd_fm801_chip_init() to
be called before we register interrupt handler and set PCI bus
mastering.

Somehow it prevents FM801-AU to work properly. Thus, partially revert
initialization order changed by commit mentioned above.

We check the availability of dma_mmap_coherent() in hw_support_mmap()
but with an ugly ifdef of lots of arch-checks.  Now we have a nice

together with CONFIG_HAS_DMA check for a cleaner and more

The ISA msnd drivers have loops fetching the ring-buffer head, tail
and size values inside the loops.  Such codes are inefficient and
fragile.

This patch optimizes it, and also adds the sanity check to avoid the
endless loops.

On this Lenovo machine, there are two front mics, and both of them are
assigned the same name "Mic", but pulseaudio can't support two mics
with the same name, as a workaround, we change the location for one of
them, then the driver will assign "Front Mic" and "Mic" for them.

ASoC: Updates for v4.13

The big news with this release is the of-graph card, this provides a
replacement for simple-card that is much more flexibile and scalable,
allowing many more systems to use a generic sound card than was possible
before:

 - The of-graph card, finally merged after a long and dedicated effort
   by Morimoto-san.
 - New widget types intended mainly for use with DSPs.
 - New drivers for Allwinner V3s SoCs, Ensonic ES8316, several classes
   of x86 machine, Rockchip PDM controllers, STM32 I2S and S/PDIF
   controllers and ZTE AUD96P22 CODECs.

For driver debugfs, debugfs_remove_recursive() is called which is not
needed as it is already done in ASoC core debugfs. And a device managed
memory need not be freed explicitly as device core frees it up. So
remove unnecessary skl_debugfs_exit().
