[ Upstream commit 0cee47cde41e22712c034ae961076067d4ac13a0 ]
The struct assertion is failed because sparse cannot parse `#pragma pack(push, 1)` and `#pragma pack(pop)` correctly. GCC's output is still 1-byte-aligned. No harm to memory layout.
The error can be filtered out by sparse-diff, but sometimes multiple lines queezed into one, making the sparse-diff thinks its a new error. I'm trying to aviod this by fixing errors.
