bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument 
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types 
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

The wavefront_send_sample() function has an integer overflow issue
when validating sample size. The header->size field is u32 but gets
cast to int for comparison with dev->freemem

Fix by using unsigned comparison to avoid integer overflow.

playing a stream and closing, the previous DMA setup was still
silently kept, and it can confuse the hardware, resulting in the
unexpected noises.  As a workaround, enforce the disablement of DMA
setups when the DMA setup is changed by the kcontrol.

174d966428 ALSA: msnd: Remove midi code 
Nothing calls snd_msndmidi_new()
  thus nothing sets chip->msndmidi_mpu
    The call to snd_msndmidi_input_read is gated on that being set,
    so snd_msndmidi_input_read() won't be called either.

This is probably a missing call to snd_msndmidi_new(), but since
this is ancient code, it's probably best to remove it (especially
since I don't have the hardware to test it).

f67c90d60f ALSA: isa/gus: remove snd_gf1_lfo_xxx() 
There is no snd_gf1_lfo_xxx() implementation, and no one is using it.
Let's remove it.

snd_gus_use_dec(), snd_gus_use_inc() and snd_gf1_print_voice_registers()
last uses were removed in 2007 by
commit e5723b41ab ("[ALSA] Remove sequencer instrument layer")

Remove them.

While there, remove big #if 0 blocks next to the code being deleted.
