d368478b29 ALSA: emu10k1: remove redundant assignment to tmp
The assignment to variable tmp is redundant as the value is never
read and a new value is assigned to tmp in the following for-loop,
so remove the assignment.
Cleans up clang warning: Value stored to 'tmp' is never read

0b36f2bd28 ALSA: emu10k1: Fix forgotten user-copy conversion in init code
The commit d42fe63d58 ("ALSA: emu10k1: Get rid of set_fs() usage")
converted the user-space copy hack with set_fs() to the direct
memcpy(), but one place was forgotten.  This resulted in the error
from snd_emu10k1_init_efx(), eventually failed to load the driver.
Fix the missing piece.

111b0cdb97 ALSA: seq: Allow the modular sequencer registration
Many drivers bind the sequencer stuff in off-load by another driver
module, so that it's loaded only on demand.  In the current code, this
mechanism doesn't work when the driver is built-in while the sequencer
is module.  We check with IS_REACHABLE() and enable only when the
sequencer is in the same level of build.

However, this is basically a overshoot.  The binder code
(snd-seq-device) is an individual module from the sequencer core
(snd-seq), and we just have to make the former a built-in while
keeping the latter a module for allowing the scenario like the above.

This patch achieves that by rewriting Kconfig slightly.  Now, a driver
that provides the manual sequencer device binding should select
CONFIG_SND_SEQ_DEVICE in a way as
	select SND_SEQ_DEVICE if SND_SEQUENCER != n

Note that the "!=n" is needed here to avoid the influence of the
sequencer core is module while the driver is built-in.

Also, since rawmidi.o may be linked with snd_seq_device.o when
built-in, we have to shuffle the code to make the linker happy.
(the kernel linker isn't smart enough yet to handle such a case.)
That is, snd_seq_device.c is moved to sound/core from sound/core/seq,
as well as Makefile.

Last but not least, the patch replaces the code using IS_REACHABLE()
with IS_ENABLED(), since now the condition meets always when enabled.

This patch is a cleanup of EMU1010 dock probing code in emu10k1 driver
to use work instead of kthread in a loop.  The work is lighter and
easier to control than kthread, in general.

Instead of a loop with the explicit sleep, we do simply
delayed-schedule the work.  At suspend/resume callbacks, the work is
canceled and restarted, respectively.

e8c44abeab ALSA: emu10k1: Fix emu1010 dock attach check
The emu1010_firmware_thread() checks the previous dock status, but a
wrong register is recorded as the last status when the dock is plugged
in.  Usually this isn't a big issue since this value gets overwritten
by the next loop after one second.  But when a dock is unplugged
immediately after plugging, it means essentially missing undock
handling.

This patch addresses it by remembering the correct register value.

d02260824e ALSA: emu10k1: Fix card shortname string buffer overflow
Some models provide too long string for the shortname that has 32bytes
including the terminator, and it results in a non-terminated string
exposed to the user-space.  This isn't too critical, though, as the
string is stopped at the succeeding longname string.

This patch fixes such entries by dropping "SB" prefix (it's enough to
fit within 32 bytes, so far).  Meanwhile, it also changes strcpy()
with strlcpy() to make sure that this kind of problem won't happen in
future, too.

driver core, we don't have to call pci_set_drvdata(pci, NULL) any
longer in each driver.

The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in
hda_intel.c.  Since this function itself releases the card instance,
we need to clear drvdata here as well, so that it won't be released
doubly in the remove callback.

e08b34e86d ALSA: emu10k1: Fix dock firmware loading
The commit [b209c4df: ALSA: emu10k1: cache emu1010 firmware] broke the
firmware loading of the dock, just (mistakenly) ignoring a different
firmware for docks on some models.  This patch revives them again.

d0ec95fe6a ALSA: emu10k1: Allow to switch hardware sampe rate on EMU
Commit 57e5c63007 "emu10k1: allow to
 disable the SRC" force hardware use only one rate (48000 hz).
EMU 0404/1010/1616 have support two hardware sampling rates (44100 and
48000 hz). This patch add check if we have EMU 0404/1010/1616 and
choose correct sample rate to restrict.
