Subject: [PATCH 5/5] i2c: geni: sdm845: dont perform DMA for the oneplus6
Date: Wed, 07 Oct 2020 17:49:35 +0000	[thread overview]
Message-ID: <20201007174736.292968-6-caleb@connolly.tech> (raw)
In-Reply-To: <20201007174736.292968-1-caleb@connolly.tech>

The OnePlus 6/T has the same issues as the c630 causing a crash when DMA
is used for i2c, so disable it.
