Subject: [PATCH 3/9] qed: avoid truncating work queue length
Date: Tue, 26 Mar 2024 23:38:02 +0100 [thread overview]
Message-ID: <20240326223825.4084412-4-arnd@kernel.org> (raw)
In-Reply-To: <20240326223825.4084412-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
clang complains that the temporary string for the name passed into
alloc_workqueue() is too short for its contents:
drivers/net/ethernet/qlogic/qed/qed_main.c:1218:3: error: 'snprintf' will always be truncated; specified size is 16, but format string expands to at least 18 [-Werror,-Wformat-truncation]
There is no need for a temporary buffer, and the actual name of a workqueue
is 32 bytes (WQ_NAME_LEN), so just use the interface as intended to avoid
the truncation.
Fixes: 59ccf86fe69a ("qed: Add driver infrastucture for handling mfw requests.")
