6.11-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 83211ae1640516accae645de82f5a0a142676897 ]
If 'frame_size' is too small or if 'round_len' is an error code, it is likely that an error code should be returned to the caller.
Actually, 'ret' is likely to be 0, so if one of these sanity checks fails, 'success' is returned.
Return -EINVAL instead.
