Subject: [PATCH] nfc: s3fwrn5: fix uninitialized ERRNO variable in probe error message
Date: Wed, 28 Jul 2021 14:28:08 +0200	[thread overview]
Message-ID: <> (raw)

Commit a0302ff5906a ("nfc: s3fwrn5: remove unnecessary label") removed
assignment to "ret" variable but it is used right after in dev_err() in
the error path.  This fixes clang warning:

    drivers/nfc/s3fwrn5/firmware.c:424:3: warning: 3rd function call argument is an uninitialized value [clang-analyzer-core.CallAndMessage]

Fixes: a0302ff5906a ("nfc: s3fwrn5: remove unnecessary label")
Reported-by: kernel test robot <>
Signed-off-by: Krzysztof Kozlowski <>
