[PATCH v3 3/5] m68k/mm/motorola: specify pmd_page() type

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Failing to specify a specific type here breaks anything that relies on the type
being explicitly known, such as page_folio().

Make explicit the type of null pointer returned here.
