Subject: [PATCH] HID: logitech-hidpp: HID: make const array consumer_rdesc_start static
Date: Fri, 10 May 2019 14:17:22 +0100	[thread overview]
Message-ID: <20190510131722.5023-1-colin.king@canonical.com> (raw)

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

Don't populate the array consumer_rdesc_start on the stack but instead
make it static. Makes the object code smaller by 88 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  59155	   9840	    448	  69443	  10f43	drivers/hid/hid-logitech-hidpp.o

After:
   text	   data	    bss	    dec	    hex	filename
  59003	   9904	    448	  69355	  10eeb	drivers/hid/hid-logitech-hidpp.o

(gcc version 8.3.0, amd64)
