    platform/x86: hp-wmi:: Mark driver struct with __refdata to prevent section mismatch warning
    
    [ Upstream commit 5b44abbc39ca15df80d0da4756078c98c831090f ]
    
    As described in the added code comment, a reference to .exit.text is ok
    for drivers registered via module_platform_driver_probe(). Make this
    explicit to prevent a section mismatch warning:
    
            WARNING: modpost: drivers/platform/x86/hp/hp-wmi: section mismatch in reference: hp_wmi_driver+0x8 (section: .data) -> hp_wmi_bios_remove (section: .exit.text)
