* Where will the variable “srctree” be set for the file “scripts/nsdeps”?

$srctree is defined by kbuild in the toplevel Makefile.

* Would you like to support a separate build directory for desired adjustments?

No, as the purpose of this script is to directly patch the kernel
sources where applicable.

* How do you think about to check error handling around such commands?

spatch emits a descriptive message on error. I will add a 'set
-e' to the script so that it aborts on errors.

I suggest to assign the name for the temporary file to a variable
which should be used by subsequent commands.

I somehow don't agree that this is an improvement to the code as the
variable would likely be something like ${source_file_tmp}. Sticking to
${source_file}.tmp does express the intent of a temporary file next to
the original source file and the reader of the code does not need to
reason about the value of ${source_file_tmp}.
