HID: i2c-hid: fix format string mismatch
[ 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.
