Description
i have no idea if the file is already close，so i may be call lfs_file_close() two times.
and free() call two times too, this cause an error.
shell we just add one line to bypass ??
static int lfs_file_rawclose(lfs_t *lfs, lfs_file_t *file) {
.....
// clean up memory
if (!file->cfg->buffer) {
lfs_free(file->cache.buffer);
file->cache.buffer = NULL; //+++++++???
}
return err;
}
