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

module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.Signed-off-by: Rusty Russell

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.The semantic patch that makes this change is available

There are some AC97 codec and board combinations that have been observed
to take a very long time to respond after the cold reset has completed.
In one case, more than 350 ms was required. To allow users to have sound
on those platforms, we'll wait up to 500ms for the codec to become
ready.As a board may have multiple codecs, with some faster than others to
reset, we add a module parameter to inform the driver which codecs
should be present.Reported-by: KotCzarny

The verb command in stac92xx_post_suspend caused the audio to stop
working after resuming from S3 mode on HP laptops with the VREF-pin
mute-LED control. Removing relevant post_suspend registering.Although removing D3 on AFG is no optimal solution, the impact should
be small in comparison with the broken S3/S4.Signed-off-by: Charles Chin

This quirk sould be reverted. It has the following probems:
1) The quirk was intended to "ASUS MV2-MX SE" motherboards only, but the
ID used matches a much broader range, potentially all boards containing a
VIA chipset model in the family of vendor VIA 0x1106 and audio device ID
0x3288, which encompasses VIA-VT82xx, VIA-VT1xx and VIA-VT20xx chipsets.2) VIA chipsets rely on azx_via_get_position() to handle correctly dma
transfers during capture. Using POS_FIX_LPIB instead of POS_FIX_VIACOMBO
leads to partially corrupted input buffers during capture. The effects
of this bug are not immediately visible, it took strong DSP expertise,
some expensive signal generator and a spectrum analyzer to identify it
and verify correct behaviour using original default.3) It's almost certain that the quirk did not fix the real problem,
if there was one. Refer to original submission:

The SigmaDSP firmware loader currently does not perform enough boundary size
checks when processing the firmware. As a result it is possible that a
malformed firmware can cause an out of bounds memory access.This patch adds checks which ensure that both the action header and the payload
are completely inside the firmware data boundaries before processing them.Signed-off-by: Lars-Peter Clausen
