This patch fixes the format strings to use the correct format type for unsigned
ints.

%h is for short ints, include/linux/mod_devicetable.h declares struct
hid_device_id (bl_entry is an instance of struct hid_device_id)
unconditionally as:
147 struct hid_device_id {
...
150 __u32 vendor;
151 __u32 product;
...
153 };
yep; LGTM

Thank you for the patch! There's 3 more of these in
drivers/hid/i2c-hid/i2c-hid-core.c if your looking to clean up some
more!

Can you make it %04x instead?
The VID/PID are usually 4 hex chars, and without the '04' format,
you'll end up having a varying length result, which is not that nice.
