[PATCH v2] misc/nvram: only declare mutex where it's used
From: Simon Richter <hidden>
Date: 2026-05-03 07:49:32
Subsystem:
char and misc drivers, the rest · Maintainers:
Arnd Bergmann, Greg Kroah-Hartman, Linus Torvalds
The ioctls using this are platform specific compatibility code. On other
platforms, this generates a warning for an unused static variable.
Fixes: 20e07af71f34d ("powerpc: Adopt nvram module for PPC64")
