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

[Markus Elfring]

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).



…
> +++ b/drivers/accel/amdxdna/aie2_pci.c

…
> +static int aie2_init(struct amdxdna_dev *xdna)

	ret = 0;
	goto release_fw;

…
> +release_fw:
> +	release_firmware(fw);
> +
> +	return ret;
> +}
…


Otherwise (in case further collateral evolution will become more desirable):
…
> +static int aie2_init(struct amdxdna_dev *xdna)
> +{
…
> +	const struct firmware *fw;

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)”?
