Subject: [PATCH 2/2] hantro: Make struct hantro_variant.init() optional
Date: Mon, 21 Jun 2021 20:11:57 -0300	[thread overview]
Message-ID: <20210621231157.226962-3-ezequiel@collabora.com> (raw)
In-Reply-To: <20210621231157.226962-1-ezequiel@collabora.com>

The hantro_variant.init() function is there for platforms
to perform hardware-specific initialization, such as
clock rate bumping.

Not all platforms require it, so make it optional.
