8637bc94f6 ALSA: asihpi - Correct headers in cached control responses.
Previously, only payload and size were correct, sufficient for reading,
but other fields produced spurious debug output.

7036b92d30 ALSA: asihpi - Remove redundant struct members.
Structs hpi_adapter and snd_card_asihpi had members that
duplicate those in underlying hpi_adapter_obj or whose info
can be retrieved using hpi_adapter_get_info().

Print less info in probe function, it can be retrieved from /proc.

Avoid name redundancy: hpi_adapter_obj.adapter_type renamed to .type

6d2d431369 ALSA: asihp: Use kcalloc instead of kzalloc to allocate array
The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.

67ada8367c ALSA: asihpi - use kzalloc()
Use kzalloc rather than kmalloc followed by memset with 0

 This considers some simple cases that are common and easy to validate
 Note in particular that there are no ...s in the rule, so all of the
 matched code has to be contiguous

 The semantic patch that makes this output is available
 in scripts/coccinelle/api/alloc/kzalloc-simple.cocci.

fd0977d0f4 ALSA: asihpi - Unsafe memory management when allocating control cache
I noticed that sound/pci/asihpi/hpicmn.c::hpi_alloc_control_cache() does
not check the return value from kmalloc(), which may fail.
If kmalloc() fails we'll dereference a null pointer and things will go bad
fast.
There are two memory allocations in that function and there's also the
problem that the first may succeed and the second may fail and nothing is
done about that either which will also go wrong down the line.
