Thanks for the fix.

Warnings are actually introduced in commit 68608b5e5063 ("firmware:
ti_sci: Add resource management APIs for ringacc, psi-l and udma").

While this patch fixes the warnings as well, I suggest to replace the
dev_dbg/dev_err traces in these functions to use the dev variable
instead of info->dev, to be consistent with the usage in the rest of the
file.

Subject: [PATCH v2 -next] firmware: ti_sci: remove set but not used variable 'dev'

Fixes gcc '-Wunused-but-set-variable' warning:
