Subject: [PATCH] staging: mmal-vchiq: If the VPU returns an error,
|
||
5 years ago
|
don't negate it
|
||
|
|
||
|
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.
