From b213ef6b72b5f1f9d333f8aca05440db4e302b46 Mon Sep 17 00:00:00 2001 From: Lorenzo Stoakes Date: Thu, 12 Jan 2023 12:39:30 +0000 Subject: [PATCH] m68k/mm/motorola: specify pmd_page() type 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.
