Subject: [PATCH 5/5] i2c: geni: sdm845: dont perform DMA for OnePlus 6 devices
Date: Thu, 12 Nov 2020 16:22:04 +0000 [thread overview]
Message-ID: <20201112161920.2671430-6-caleb@connolly.tech> (raw)
In-Reply-To: <20201112161920.2671430-1-caleb@connolly.tech>
The OnePlus 6/T has the same issue as the Yoga c630 causing a crash when DMA
is used for i2c, so disable it.
