Well. If one call to s6e63m0_panel_send_sequence() returns -ENOMEM and
another call returns -EIO (for example), this function will return some
other, incorrect errno.
Which is a rather minor problem, unless some caller is explicitly
looking for some particular error code, which doesn't happen often.
