e480c0991d ASoC: tas2781: Remove redundant initialization of pointer 'data'
The pointer 'data' being initialized with a value that is never read, it
is being re-assigned inside a while-loop. The initialization is redundant
and can be removed.

Cleans up clang scan build warning
sound/soc/codecs/tas2781-fmwlib.c:1534:17: warning: Value stored to
'data' during its initialization is never read [deadcode.DeadStores]

0205f3753d Merge tag 'asoc-v6.8' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v6.8

This is a relatively quiet release, there's a lot of driver specific
changes and the usual high level of activity in the SOF core but the
one big core change was Mormioto-san's work to support more N:M
CPU:CODEC mapping cases.  Highlights include:

 - Enhanced support for N:M CPU:CODEC mappings in the core and in
   audio-graph-card2.
 - Support for falling back to older SOF IPC versions where firmware for
   new versions is not available.
 - Support for notification of control changes generated by SOF firmware
   with IPC4.
 - Device tree support for describing parts of the card which can be
   active over suspend (for very low power playback or wake word use
   cases).
 - ACPI parsing support for the ES83xx driver, reducing the number of
   quirks neede for x86 systems.
 - Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm
   SM8250, SM8550, SM8650 and X1E80100.
 - Removal of Freescale MPC8610 support, the SoC is no longer supported
   by Linux.

ee00330a5b ASoC: tas2781: add support for FW version 0x0503
Layout of FW version 0x0503 is compatible with 0x0502.
Already supported by TI's tas2781-linux-driver tree.

f32c80d342 ASoC: tas2781: check the validity of prm_no/cfg_no
Add additional checks for program/config numbers to avoid loading from
invalid addresses.

If prm_no/cfg_no is negative, skip uploading program/config.

The tas2781-hda driver caused a NULL pointer dereference after loading
module, and before first runtime_suspend.

the state was:
tas_priv->cur_conf = -1;
tas_priv->tasdevice[i].cur_conf = 0;
program = &(tas_fmw->programs[-1]);

BUG: kernel NULL pointer dereference, address: 0000000000000010

fixed m68k compiling issue: mapping table can save code field; storing the
dev_idx as a member of block can reduce unnecessary  time and system
resource comsumption of dev_idx mapping every time the block data writing
