[PATCH 6.19 17/86] i2c: imx: zero-initialize dma_slave_config for eDMA

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Anthony Pighin <anthony.pighin@nokia.com>

commit 39ed7d89b973329cc5c764b65ba6302b17b1907e upstream.

commit 66d88e16f204 ("dmaengine: fsl-edma: read/write multiple registers
in cyclic transactions") causes fsl_edma_fill_tcd() to read
dst_port_window_size and src_port_window_size when building transfer
control descriptors.

Initialize the structure so unset fields are explicitly zero.
