crypto: tegra: Use separate buffer for setkey
...
The buffer which sends the commands to host1x was shared for all tasks
in the engine. This causes a problem with the setkey() function as it
gets called asynchronous to the crypto engine queue. Modifying the same
cmdbuf in setkey() will corrupt the ongoing host1x task and in turn
break the encryption/decryption operation. Hence use a separate cmdbuf
for setkey().

crypto: tegra - Remove an incorrect iommu_fwspec_free() call in tegra_se_remove()
...
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.

drivers: Drop inline from driver remove wrapper
...
The driver remove function is a function pointer and therefore, it does
not make sense to define the function as an 'inline'. Update the
coccinelle script and drivers to remove the inline statement.
