[adriendesp]

Description / Steps to reproduce the issue

Where : In the file fs/vfs/fs_pseudofile.c, in method pseudofile_munmap, since #13443
When : When CONFIG_PSEUDOFS_FILE=y is enabled
What : The following build error is returned :

libm/lib_nanl.c vfs/fs_pseudofile.c: In function 'pseudofile_munmap': vfs/fs_pseudofile.c:367:7: error: 'ret' undeclared (first use in this function) 367 | ret = OK; | ^~~
