I asked Umang to add the Fixes tag based on the patch description and
based on that it seemed like a behavior change just from looking at
the patch.
But actually you are right that the fixes tag is not required.
The vchiq_send_remote_use() function is never called (dead code). The
vchiq_send_remote_use_active() function now returns a mix of custom
error codes and negative error codes. (Ugly). The caller only tests
for VCHIQ_SUCCESS so this code does not change behavior. I really feel
like the commit description needs to be clearer on this.
The fixes tag is not really about stable. Stable uses the tag, but the
fixes tag is appropriate whenever there is a bug fix.
