USB: m66592-udc: reduce size of data structure.
Poking around with pahole, we see that m66592 handily shoves a u16 in between larger types on 2 separate occasions leaving us with 2 2-byte holes: struct m66592 { ... /* size: 1196, cachelines: 38 */ /* sum members: 1192, holes: 2, sum holes: 4 */ /* last cacheline: 12 bytes */ }; /* definitions: 1 */ Pairing them gets back 4-bytes: struct m66592 { ... /* size: 1192, cachelines: 38 */ /* last cacheline: 8 bytes */ }; /* definitions: 1 */ Unfortunately it's not enough to save a cacheline with this massive structure, but every byte helps.
