From 833c2c083856ef3077b51c908ec401fa0a130d57 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Tue, 22 Oct 2019 09:34:59 -0700 Subject: Input: st1232 - note that the receive buffer is DMA-safe The receiving buffer is allocated separately from the main driver data structure, and is naturally DMA-safe, so mark it as such when building I2C transfer message.
