Currently the error message uses 'np->full_name' which leads to a very verbose
log that contains the full path of the node.
We can have a concise log by using pdev->name instead.

The 'name' array is currently stored inside the fsl_asrc private structure only
for registering the interrupt name.
This can be simplified by registering it with dev_name() instead.

After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.
Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under sound/.

------------[ dump end ]------------
=============================================================================
2741 /*
2742 * Oi! Can't be having __GFP_FS allocations with IRQs disabled.

2744 if (DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags)))
2745 return;
=============================================================================
By looking at 2744 line, we can get that it's because regcache_rbtree_write()
would call kmalloc() with GFP flag if it couldn't find an existing block to
insert nodes while this kmalloc() call is inside a spin_lock_irq_save pair,
i.e. IRQs disabled.
Even though this may be a bug that should be fixed, I still try to send this
patch as a quick fix (work around) since it does no harm to assign default
values of every registers when using regcache.

Use strncpy() instead of strcpy(). That's not a security issue, as the
source buffer is taken from DT nodes, but we should still enforce bound
checks. Spotted by Coverity.

The Asynchronous Sample Rate Converter (ASRC) converts the sampling rate of a
signal associated with an input clock into a signal associated with a different
output clock. The driver currently works as a Front End of DPCM with other Back
Ends DAI links such as ESAI<->CS42888 and SSI<->WM8962 and SAI. It converts the
original sample rate to a common rate supported by Back Ends for playback while
converts the common rate of Back Ends to a desired rate for capture. It has 3
pairs to support three different substreams within totally 10 channels.
