Subject: sh_eth: fix DMA channel misreporting
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3c78658e26b3bbb29f646416f52f4b4d875de471;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

sh_eth: fix DMA channel misreporting

Currently 'ifconfig' for the Ethernet devices handled by this driver  shows
"DMA chan: ff" while the driver doesn't use any DMA channels. Not assigning
a value to 'net_device::dma' causes 'ifconfig'  to  correctly not report  a
DMA channel.
