9d2e19e349 ALSA: gus: Fix repeated probes of snd_gus_create()
GUS card object may be repeatedly probed for the legacy ISA devices,
and the behavior doesn't fit with the devres resource management.

Revert partially back to the classical way for the snd_gus_card
object, so that the repeated calls of snd_gus_create() are allowed.

5b88da3c80 ALSA: gus: Allocate resources with device-managed APIs
This patch converts the resource management in ISA gus drivers with
devres as a clean up.  Each manual resource management is converted
with the corresponding devres helper.  The remove callback became
superfluous and dropped.

This should give no user-visible functional changes.

310efd3aab ALSA: gus: Fix assignment in if condition
ISA GUS driver code contains lots of assignments in if condition,
which is a bad coding style that may confuse readers and occasionally
lead to bugs.

This patch is merely for coding-style fixes, no functional changes.

Fix smatch warning:
sound/isa/gus/gus_main.c:396 snd_gus_check_version() error:
 strcpy() 'card->longname' too large for 'card->shortname' (80 vs 32)

Even if this is not a real bug since the longest length of card->longname
now is 31, replace strcpy() with strscpy() in order to avoid possible
future mistake.

1dacca7fa1 Revert "ALSA: gus: add a check of the status of snd_ctl_add"
This reverts commit 0f25e000cb4398081748e54f62a902098aa79ec1.

Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.

Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted.  It will be fixed up "correctly" in a
later kernel change.

The original commit did nothing if there was an error, except to print
out a message, which is pointless.  So remove the commit as it gives a
"false sense of doing something".

For a sake of code simplification, remove the init and the exit
entries that do nothing.

Notes for readers: actually it's OK to remove *both* init and exit,
but not OK to remove the exit entry.  By removing only the exit while
keeping init, the module becomes permanently loaded; i.e. you cannot
unload it any longer!

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
