I applied this patch to the 4.8.4 kernel driver (that I'm currently running) and it caused nothing but "frontend 0/0 timed out while tuning". Is there another patch that should be used in conjunction with this? If not, this patch breaks the gp8psk driver. Thanks. On Tue, Oct 11, 2016 at 3:09 AM,

[PATCH v2 18/31] gp8psk: don't do DMA on stack

2016-10-11 Thread Mauro Carvalho Chehab
The USB control messages require DMA to work. We cannot pass a stack-allocated buffer, as it is not warranted that the stack would be into a DMA enabled area. Signed-off-by: Mauro Carvalho Chehab --- drivers/media/usb/dvb-usb/gp8psk.c | 14 -- 1 file
