Subject: [PATCH 4.9 09/29] HID: i2c-hid: fix format string mismatch
Date: Tue,  8 Jun 2021 20:27:03 +0200
Message-ID: <20210608175928.120985240@linuxfoundation.org> (raw)
In-Reply-To: <20210608175927.821075974@linuxfoundation.org>

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit dc5f9f55502e13ba05731d5046a14620aa2ff456 ]

clang doesn't like printing a 32-bit integer using %hX format string:

drivers/hid/i2c-hid/i2c-hid-core.c:994:18: error: format specifies type 'unsigned short' but the argument has type '__u32' (aka 'unsigned int') [-Werror,-Wformat]
                 client->name, hid->vendor, hid->product);
                               ^~~~~~~~~~~
drivers/hid/i2c-hid/i2c-hid-core.c:994:31: error: format specifies type 'unsigned short' but the argument has type '__u32' (aka 'unsigned int') [-Werror,-Wformat]
                 client->name, hid->vendor, hid->product);
                                            ^~~~~~~~~~~~

Use an explicit cast to truncate it to the low 16 bits instead.
