Subject: [PATCH 6/9] Input: IMS: fix printf string overflow
Date: Tue, 26 Mar 2024 23:38:05 +0100 [thread overview]
Message-ID: <20240326223825.4084412-7-arnd@kernel.org> (raw)
In-Reply-To: <20240326223825.4084412-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
clang warns about a string overflow in this driver
drivers/input/misc/ims-pcu.c:1802:2: error: 'snprintf' will always be truncated; specified size is 10, but format string expands to at least 12 [-Werror,-Wformat-truncation]
drivers/input/misc/ims-pcu.c:1814:2: error: 'snprintf' will always be truncated; specified size is 10, but format string expands to at least 12 [-Werror,-Wformat-truncation]
Make the buffer a little longer to ensure it always fits.
Fixes: 628329d52474 ("Input: add IMS Passenger Control Unit driver")
