Three module clock error handling improvements:
- use devm_clk_get() so the clock instance can be freed if
devm_gpiochip_add_data() fails later on
- switch to clk_prepare_enable() so the driver is ready whenever the
lantiq target switches to the common clock framework
- disable the clock again (using clk_disable_unprepare()) if
devm_gpiochip_add_data()
All of these are virtually no-ops with the current lantiq target.
However, these will be relevant if we switch to the common clock
framework.

Return early if devm_gpiochip_add_data() returns an error instead of
having two consecutive "if (!ret) ..." statements.
Also make xway_stp_hw_init() return void because it unconditionally
returns 0. While here also update the kerneldoc comment for
xway_stp_hw_init().
These changes makes the error handling within the driver consistent.
No functional changes intended.

[2] arch/nios2/Kconfig.debug
config TRACE_IRQFLAGS_SUPPORT
def_bool y
[1] is included before [2]. In the Kconfig syntax, the first one
is effective. So, TRACE_IRQFLAGS_SUPPORT is always 'n'.
The second define in arch/nios2/Kconfig.debug is dead code.

This is a bug in clang that will be fixed in the future, but in order

The best solution I could come up with is to move the BIT() usage

It makes it easier for common code to work with snd_soc_dai_set_channel_map()
by distinguishing between operation not being supported and an error.
This is done inline with others snd_soc_dai.* apis.

ACPICA commit 1ca34b1a7b960ef321eae5dcddfff77707c88aef
There have been several places that have been calling functions
regarding module level code blocks. This change removes all old
vestiges in the codebase. This is dead code.

ACPICA commit 76658f55d8cc498a763bdb92f8e0d934822a129c
For the objects that are created by default (_GPE, _SB_, etc)
there is no need to use the heavyweight ns_lookup function.
Instead, simply create each object and link it in as the namespace
is built.

While mips might architecturally have the uncached segment all the time,
the infrastructure to use it is only need on platforms where DMA is
at least partially incoherent. Only select it for those configuration
to fix a build failure as the arch_dma_prep_coherent symbol is also only
provided for non-coherent platforms.
