a34993a279 misc: hisi_hikey_usb: change the DT schema

While here, add error messages, in order to help discovering

83c510568e misc: rtsx: Remove usage of the deprecated "pci-dma-compat.h" API
In [1], Christoph Hellwig has proposed to remove the wrappers in
include/linux/pci-dma-compat.h.

Some reasons why this API should be removed have been given by Julia
Lawall in [2].

Finally, Arnd Bergmann reminded that the documentation was updated 11 years
ago to only describe the modern linux/dma-mapping.h interfaces and mark the
old bus-specific ones as no longer recommended, see commit 216bf58f40
("Documentation: convert PCI-DMA-mapping.txt to use the generic DMA API").

A coccinelle script has been used to perform the needed transformation
Only relevant parts are given below.

e5f71d60ff /dev/mem: nowait zero/null ops
Make read_iter_zero() to honor IOCB_NOWAIT, so /dev/zero can be
advertised as FMODE_NOWAIT. It's useful for io_uring, which needs it to
apply certain optimisations when doing I/O against the device.

Set FMODE_NOWAIT for /dev/null as well, it never waits and therefore
trivially meets the criteria.

   id->string translators.

 - Add a file generated during the documentation build to .gitignore.

 - Add an option to build without libbfd, as some distros, like Debian
   consider its ABI unstable.

 - Add support to print a textual representation of IBS raw sample data
   in 'perf report'.

 - Fix bpf 'perf test' sample mismatch reporting

 - Fix passing arguments to stackcollapse report in a 'perf script'
   python script.

 - Allow build-id with trailing zeros.

 - Look for ImageBase in PE file to compute .text offset.
