From a417ab334dccb603f6296cbf04c9f8059bc252eb Mon Sep 17 00:00:00 2001 From: Justin Stitt Date: Wed, 16 Aug 2023 18:26:44 +0000 Subject: mtd: maps: fix -Wvoid-pointer-to-enum-cast warning When building with clang 18 I see the following warning: | drivers/mtd/maps/physmap-versatile.c:209:25: warning: cast to smaller | integer type 'enum versatile_flashprot' from 'const void *' [-Wvoid-pointer-to-enum-cast] | 209 | versatile_flashprot = (enum versatile_flashprot)devid->data; This is due to the fact that `devid->data` is a void* while `enum versatile_flashprot` has the size of an int. Cast `devid->data` to a uintptr_t to silence the above warning for clang builds using W=1.
