Subject: [PATCH 11/18] crypto: pkcs7: Use match_string() helper to simplify the code
Date: Wed, 09 Dec 2020 12:15:48 +0000	[thread overview]
Message-ID: <160751614848.1238376.4757193989177203825.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <160751606428.1238376.14935502103503420781.stgit@warthog.procyon.org.uk>

From: YueHaibing <yuehaibing@huawei.com>

match_string() returns the array index of a matching string.
Use it instead of the open-coded implementation.
