Manivannan Sadhasivam ea3357c6cf bus: mhi: ep: Do not allocate event ring element on stack ... [ Upstream commit 987fdb5a43a66764808371b54e6047834170d565 ] It is possible that the host controller driver would use DMA framework to write the event ring element. So avoid allocating event ring element on the stack as DMA cannot work on vmalloc memory.
