Hello. And thank you very much all for your work on linux-libre.
When trying to compile GNU linux-libre 4.16.0 for a wandboard quad
(IMX6Q) I got a NULL pointer dereference.
Aparently now sdma_load_firmware(NULL,NULL)
gets called from
and when it tries to print a nice error message that the 1st parameter
(fw) was NULL it tries to use context->dev as an argument, but context
is NULL too.
I'm trying to just change reject_firmware_nowait to pass context instead of
NULL, but I wonder if this NULL was deliberate and I'll break something
somewhere else ?
