clang warns:
drivers/scsi/elx/efct/efct_hw.c:1523:17: warning: address of array
'ctx->buf' will always evaluate to 'true' [-Wpointer-bool-conversion]
(!ctx->buf ? U32_MAX : *((u32 *)ctx->buf)));
~~~~~~^~~
buf is an array in the middle of a struct so deferencing it is not a
problem as long as ctx is not NULL. Eliminate the check, which fixes the
warning.

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 Restructured Text 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.
