gcc -Wextra warns about mixing drbd_state_rv with drbd_ret_code
in a couple of places:
drivers/block/drbd/drbd_nl.c: In function 'drbd_adm_set_role':
drivers/block/drbd/drbd_nl.c:777:14: warning: comparison between 'enum drbd_state_rv' and 'enum drbd_ret_code' [-Wenum-compare]
777 | if (retcode != NO_ERROR)
| ^~

2690 | retcode = conn_request_state(connection, NS(conn, C_UNCONNECTED), CS_VERBOSE);

drivers/block/drbd/drbd_nl.c: In function 'drbd_adm_disconnect':
drivers/block/drbd/drbd_nl.c:2803:11: warning: implicit conversion from 'enum drbd_state_rv' to 'enum drbd_ret_code' [-Wenum-conversion]
2803 | retcode = rv; /* FIXME: Type mismatch. */
| ^
In each case, both are passed into drbd_adm_finish(), which just takes
a 32-bit integer and is happy with either, presumably intentionally.
Restructure the code to pass either type directly in there in most
cases, avoiding the warnings.

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.
