[PATCH v2 04/11] mmc: bcm2835: stop setting chan_config->slave_id

From: Arnd Bergmann <arnd@kernel.org>
Date: 2021-11-22 22:23:06
Also in: alsa-devel, dmaengine, dri-devel, linux-arm-msm, linux-mmc, linux-serial, linux-spi, linux-staging, linux-tegra, lkml
Subsystem: multimedia card (mmc), secure digital (sd) and sdio subsystem, the rest · Maintainers: Ulf Hansson, Linus Torvalds

From: Arnd Bergmann <arnd@arndb.de>

The field is not interpreted by the DMA engine driver, as all the data
is passed from devicetree instead. Remove the assignment so the field
can eventually be deleted.
