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

From: Christophe JAILLET christophe.jaillet@wanadoo.fr
[ Upstream commit 8d7c52cb4184d3dc26dde62b4f5acd48de0768ae ]
The only iommu function call in this driver is a tegra_dev_iommu_get_stream_id() which does not allocate anything and does not take any reference.
So there is no point in calling iommu_fwspec_free() in the remove function.
Remove this incorrect function call.
