Subject: [PATCH -next] mm/hmm: remove set but not used variable 'devmem'
Date: Sat, 1 Dec 2018 02:06:11 +0000 [thread overview]
Message-ID: <1543629971-128377-1-git-send-email-yuehaibing@huawei.com> (raw)
Fixes gcc '-Wunused-but-set-variable' warning:
mm/hmm.c: In function 'hmm_devmem_ref_kill':
mm/hmm.c:995:21: warning:
variable 'devmem' set but not used [-Wunused-but-set-variable]
It not used any more since commit 35d39f953d4e ("mm, hmm: replace
hmm_devmem_pages_create() with devm_memremap_pages()")
