Subject: [PATCH v2 14/14] media: staging: rkisp1: params: no need to lock default config
Date: Sat, 15 Aug 2020 12:37:34 +0200 [thread overview]
Message-ID: <20200815103734.31153-15-dafna.hirschfeld@collabora.com> (raw)
In-Reply-To: <20200815103734.31153-1-dafna.hirschfeld@collabora.com>
In the function 'rkisp1_params_config_parameter' the lock
is taken while applying the default config. But the lock
only needs to protect the buffers list and the 'is_streaming'
field, so move the locking to lock only what is needed.
