problem with building v3.6.0 in shell_stop

[lukas-fwdev]

Hi,
I am facing a problem when migrating from v3.5.0 to v3.6.0.
I get the error:
c:/myPath/zephyr-sdk-0.16.1/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd.exe: zephyr/libzephyr.a(shell.c.obj): in function 'shell_stop': P:/myPath/zephyr/subsys/shell/shell.c:1463: undefined reference to 'z_shell_log_backend_disable' collect2.exe: error: ld returned 1 exit status

I can see that the call of z_shell_log_backend_disable() inside shell_stop function was introduced with PR #67400 from @jakub-uC .
I am wondering if there is missing a guard around this call like it is done in function instance_uninit() in the same file.
When changing the simple function call to:
if (IS_ENABLED(CONFIG_SHELL_LOG_BACKEND)) { z_shell_log_backend_disable(sh->log_backend); }
everything is working fine.

Does anyone of you know, if I just missed any configuration or similiar, or if this is a real bug?

Thanks in advance!

The z_shell_log_backend_disable won't be available if CONFIG_SHELL_LOG_BACKEND is off.
It is a bug, forgotten IS_ENABLED(CONFIG_SHELL_LOG_BACKEND) condition.

Thanks, I opened this as an issue.
