From 8aa29f192ca675746ab4f39e46a5fd712a76faa6 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 1 Mar 2018 15:07:20 -0800 Subject: scsi: ufs: Fix kernel-doc errors and warnings 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 Cc: Vivek Gautam Cc: Stanislav Nijnikov Signed-off-by: Martin K.
