Documentation/filesystems/porting.rst:
**mandatory**
Calling conventions for vfs_parse_fs_string() have changed; it does *not*
take length anymore (value ? strlen(value) : 0 is used). If you want
a different length, use
vfs_parse_fs_qstr(fc, key, &QSTR_LEN(value, len))
instead.
IOW, your drm_gem_add_fc_param(fc, key, value) is an exact equivalent
of vfs_parse_fs_string(fc, key, value) now.
