Since commit 3a025e1d1c2e ("Add optional check for bad kernel-doc
comments") building with W=1 causes warnings to appear for issues
in kernel-doc headers. This patch avoids that the following warnings
are reported when building with W=1:

drivers/scsi/device_handler/scsi_dh_alua.c:867: warning: No description found 
for parameter 'pg'
drivers/scsi/device_handler/scsi_dh_alua.c:867: warning: No description found 
for parameter 'sdev'
drivers/scsi/device_handler/scsi_dh_alua.c:867: warning: No description found 
for parameter 'qdata'
drivers/scsi/device_handler/scsi_dh_alua.c:867: warning: No description found 
for parameter 'force'
