Subject: [PATCH v1 1/1] libnvdimm/labels: Get rid of redundant 'else'
Date: Wed, 5 Nov 2025 19:37:43 +0100 [thread overview]
Message-ID: <20251105183743.1800500-1-andriy.shevchenko@linux.intel.com> (raw)
In the snippets like the following
if (...)
return / goto / break / continue ...;
else
...
the 'else' is redundant. Get rid of it.
