Subject: [PATCH][next] drm/i915: remove redundant assignement to variable err
Date: Mon, 15 Apr 2024 10:56:59 +0100	[thread overview]
Message-ID: <20240415095659.482989-1-colin.i.king@gmail.com> (raw)

The variable err is being assigned a value 0 that is never read, the
break statement escapes a do-while loop and then the code returns
without referencing err. The assignment is redundant and can be
removed.

Cleans up clang scan build warning:
drivers/gpu/drm/i915/gem/selftests/i915_gem_mman.c:1075:5: warning: Value
stored to 'err' is never read [deadcode.DeadStores]
