Subject: [PATCH -next 1/2] ACPI: processor_throttling: Remove redundant initialization of 'obj'
Date: Thu, 10 Jun 2021 17:40:38 +0800 [thread overview]
Message-ID: <1623318039-57133-1-git-send-email-yang.lee@linux.alibaba.com> (raw)
'obj' is being initialized, however this value is never read as
'obj' is assigned an updated value later. Remove the redundant
initialization.
Clean up clang warning:
drivers/acpi/processor_throttling.c:409:20: warning: Value stored to
'obj' during its initialization is never read
[clang-analyzer-deadcode.DeadStores]
