[PATCH 09/50] staging: mmal-vchiq: If the VPU returns an error, don't negate it

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

 



From: Dave Stevenson <dave.stevenson@xxxxxxxxxxxxxxx>

There is an enum for the errors that the VPU can return.
port_parameter_get was negating that value, but also using -EINVAL
from the Linux error codes.
Pass the VPU error code as positive values. Should the function
need to pass a Linux failure, then return that as negative.
