Re: [PATCH V2 01/10] accel/amdxdna: Add a new driver for AMD AI Engine

If you temporarily find the circumstances too challenging for applications
of scope-based resource management, I suggest to use the following statements instead
(so that a bit of redundant code can be avoided).

	ret = 0;
	goto release_fw;

Otherwise (in case further collateral evolution will become more desirable):

I propose to take another software design option better into account.

* You may reduce the scope of such a local variable.

* How do you think about to use the attribute “__free(firmware)”?
