Avoid that the kernel-doc tool complains about mismatches between kernel-doc headers and function definitions. Avoid that errors like the following are reported when building the UFS driver with W=1: drivers/scsi/ufs/tc-dwc-g210-pci.c:60: error: Cannot parse struct or union! drivers/scsi/ufs/tc-dwc-g210-pltfrm.c:26: warning: cannot understand function prototype: 'struct ufs_hba_variant_ops tc_dwc_g210_20bit_pltfm_hba_vops = ' Signed-off-by: Bart Van Assche <bart.vanassche@wdc.com> Cc: Vivek Gautam <vivek.gautam@codeaurora.org> Cc: Stanislav Nijnikov <stanislav.nijnikov@wdc.com> Signed-off-by: Martin K.
