[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

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

From: Ricardo Ribalda <ribalda@xxxxxxxxxxxx>

commit 8bbae288a85abed6a1cf7d185d8b9dc2f5dcb12c upstream.

Allow devices to have dma operations beyond 4K, and avoid warnings such
as:

DMA-API: dwc3 a600000.usb: mapping sg segment longer than device claims to support [len=86016] [max=65536]
