Subject: [PATCH v2 2/4] interconnect: Always call pre_aggregate before aggregate
Date: Wed, 21 Jul 2021 10:54:30 -0700	[thread overview]
Message-ID: <20210721175432.2119-3-mdtipton@codeaurora.org> (raw)
In-Reply-To: <20210721175432.2119-1-mdtipton@codeaurora.org>

The pre_aggregate callback isn't called in all cases before calling
aggregate. Add the missing calls so providers can rely on consistent
framework behavior.

Fixes: d3703b3e255f ("interconnect: Aggregate before setting initial bandwidth")
