ALSA: hda: check make_exec_verb() return value If given a -1 cmd parameter then make_exec_verb() returns -1 without setting the res output value. Prior to this change snd_hda_codec_read() assumed that make_exec_verb() unconditionally set res regardless of the cmd value. This change explicitly checks the make_exec_verb() return value before consuming the potentially unset res value.
