Subject: [PATCH] HID: uclogic: Fix warning in uclogic_rdesc_template_apply

Building with Sparse enabled prints this warning:

    warning: incorrect type in assignment (different base types)
        expected signed int x
        got restricted __le32 [usertype]

Cast the return value of cpu_to_le32() to fix the warning.

Fixes: 08177f40bd00 ("HID: uclogic: merge hid-huion driver in hid-uclogic")
