From: Sean Christopherson <seanjc@xxxxxxxxxx> Adjust a variety of functions in mmu.c to put the function return type on the same line as the function declaration. As stated in the Linus specification: But the "on their own line" is complete garbage to begin with. That will NEVER be a kernel rule. We should never have a rule that assumes things are so long that they need to be on multiple lines. We don't put function return types on their own lines either, even if some other projects have that rule (just to get function names at the beginning of lines or some other odd reason). Leave the functions generated by BUILD_MMU_ROLE_REGS_ACCESSOR() as-is, that code is basically illegible no matter how it's formatted. No functional change intended.
