Using the address operator on the array doesn't work:
./include/linux/seq_buf.h:27:27: error: initialization of ‘char *’
from incompatible pointer type ‘char (*)[128]’
[-Werror=incompatible-pointer-types]
27 | .buffer = &__ ## NAME ## _buffer, \
| ^
Apart from fixing that, we can improve DECLARE_SEQ_BUF() by using a
compound literal to define the buffer array without attaching a name
to it. This makes the macro a single statement, allowing constructs
such as:
static DECLARE_SEQ_BUF(my_seq_buf, MYSB_SIZE);
to work as intended.

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.
