e6e8c82b97 ALSA: atmel: Drop superfluous PCM preallocation error checks
snd_pcm_lib_preallocate_pages() and co always succeed, so the error
check is simply redundant.  Drop it.

b06898d119 ASoC: Updates for v4.14
This is quite a large release by volume of patches and diff, a lot of
 that is mechanical cleanup patches but it's great to also see a range of
 vendors actively working on adding new features and fixing issues in
 their drivers.  Intel and Realtek have been especially active here.
 
  - Continued work towards moving everything to the component model from
    Morimoto-san.
  - Use of devres for jack detection GPIOs, eliminating some potential
    resource leaks.
  - Jack detection support for Qualcomm MSM8916.
  - Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake
    systems with RT5663, Realtek RT274, TI TLV320AIC32x6 and Wolfson

 Other than that, a few minor driver core and debugfs changes.  There are

337bb336b9 ALSA: atmel_abdac: clk_round_rate() can return a zero upon error
Treat both negative and zero return values from clk_round_rate()
as errors.  This is needed since subsequent patches will convert
clk_round_rate()'s return value to be an unsigned type, rather
than a signed type, since some clock sources can generate rates higher
than (2^31)-1 Hz.

Eventually, when calling clk_round_rate(), only a return value of
zero will be considered a error; all other values will be
considered valid rates.  The comparison against values less than
0 is kept to preserve the correct behavior in the meantime.

e2b35f3dbf dmaengine/dw_dmac: Fix dw_dmac user drivers to adapt to slave_config changes
There are few existing user drivers of dw_dmac. They will break as soon as we
remove unused fields from struct dw_dma_slave. This patch focuses to fix these
user drivers to use dma_slave_config() routine.

28f65c11f2 treewide: Convert uses of struct resource to resource_size(ptr)
Several fixes as well where the +1 was missing.

Done via coccinelle scripts like:

@@
struct resource *ptr;
@@

- ptr->end - ptr->start + 1
+ resource_size(ptr)

and some grep and typing.

Mostly uncompiled, no cross-compilers.
