Subject: [PATCH AUTOSEL 5.4 091/205] crypto: arm64/aes-neonbs - add return value of skcipher_walk_done() in __xts_crypt()
From: Yunfeng Ye <yeyunfeng@...wei.com>
[ Upstream commit 9b537997b669c42cec67893538037e8d1c83c91c ]
A warning is found by the static code analysis tool:
"Identical condition 'err', second condition is always false"
Fix this by adding return value of skcipher_walk_done().
Fixes: 67cfa5d3b721 ("crypto: arm64/aes-neonbs - implement ciphertext stealing for XTS")
