Subject: [Nouveau] [PATCH linux-next] drm/nouveau/mmu/gp100-: drop unneeded assignment in the if condition.
Date: Fri, 20 Aug 2021 19:14:47 -0700 [thread overview]
Message-ID: <20210821021447.27097-1-luo.penghao@zte.com.cn> (raw)
From: Luo penghao <luo.penghao@zte.com.cn>
In order to keep the code style consistency of the whole file,
the 'inst' assignments should be deleted.
The clang_analyzer complains as follows:
drivers/gpu/drm/nouveau/nvkm/subdev/mmu/vmmgp100.c:499:8: warning:
Although the value storedto 'inst' is used in the enclosing expression,
the value is never actually read from 'inst'.
