Re: [PATCH] mmc: renesas_sdhi: sys_dmac: abort DMA synced to avoid timeouts

[Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>]

While the patch does not fix the timeout issue (also verified using an
Alt board), it does fix this follow-up issue here:

[  191.485194] ------------[ cut here ]------------
[  191.490296] WARNING: CPU: 0 PID: 698 at kernel/dma/debug.c:498 add_dma_entry+0x158/0x180
[  191.499397] DMA-API: exceeded 7 overlapping mappings of cacheline 0x0117cc3a

So, I think we want this patch nonetheless but I need to rephrase the
commit message.
