77a58ba7c6The spi subsystem has tracing, which is very convenient when debugging problems. Add tracing for spi-mem too so that accesses that skip the spi subsystem can still be seen. The format is roughly based on the existing spi tracing. We don't bother tracing the op's address because the tracing happens while the memory is locked, so there can be no confusion about the matching of start and stop. The conversion of cmd/addr/dummy to an array is directly analogous to the conversion in the latter half of spi_mem_exec_op.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
