Subject: [PATCH][next] net: hns3: fix return of random stack value
Date: Wed, 10 Feb 2021 13:28:41 -0600 [thread overview]
Message-ID: <20210210192841.GA838928@embeddedor> (raw)
Currently, a random stack value is being returned because variable
_ret_ is not properly initialized. This variable is actually not
used anymore and it should be removed.
Fix this by removing all instances of variable ret and return 0.
Fixes: 64749c9c38a9 ("net: hns3: remove redundant return value of hns3_uninit_all_ring()")
Addresses-Coverity-ID: 1501700 ("Uninitialized scalar variable")
Signed-off-by: Gustavo A. R. Silva <gustavoars@kernel.org>
