[PATCH 05/43] target/ppc/mmu_common.c: Remove another single use local variable
Posted by BALATON Zoltan 6 months ago
In ppc6xx_tlb_pte_check() the pteh variable is used only once to
compare to the h parameter of the function. Inline its value and use
pteh name for the function parameter which is more descriptive.
