Subject: [PATCH] scsi: ufs: tc-dwc-g210: make arrays static, reduces object code size
Date: Tue, 12 Sep 2017 12:32:28 +0100	[thread overview]
Message-ID: <20170912113228.1389-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

Don't populate const arrays on the stack, instead make them
static.  Makes the object code smaller by over 740 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
   3840	    208	      0	   4048	    fd0	drivers/scsi/ufs/tc-dwc-g210.o

After:
   text	   data	    bss	    dec	    hex	filename
   2679	    624	      0	   3303	    ce7	drivers/scsi/ufs/tc-dwc-g210.o
