Subject: ALSA: hda - Fix static checker warning in patch_hdmi.c
From: David Henningsson <[email protected]>
commit 360a8245680053619205a3ae10e6bfe624a5da1d upstream.
The static checker warning is:
sound/pci/hda/patch_hdmi.c:460 hdmi_eld_ctl_get() error: __memcpy() 'eld->eld_buffer' too small (256 vs 512)
I have a hard time figuring out if this can ever cause an information leak (I don't think so), but nonetheless it does not hurt to increase the robustness of the code.
