| Subject: NOUPSTREAM: ANDROID: export: Disable symbol trimming on modules |
| |
| Trimming non-whitelisted symbols from modules will be useful once we |
| introduce GKI modules, but in the meantime it causes pain downstream for |
| out-of-tree modules as vendors will have to whitelist the symbols they |
| need. |
| |
| The right solution would be to apply the trimming or not to a module |
| based on an explicit list of GKI modules, but as we currently don't have |
| any (nor we have a good way to differentiate them in the kernel build |
| system), let's simply disable the trimming for all modules altogether, |
| and get things unblocked for GKI 1.0. |
