Subject: [PATCH 6/9] Input: IMS: fix printf string overflow

From: Arnd Bergmann <arnd@...db.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")
