Subject: [PATCH] HID: lg-g15: make a const array static, makes object smaller
Date: Thu,  4 Feb 2021 17:27:48 +0000	[thread overview]
Message-ID: <20210204172748.107406-1-colin.king@canonical.com> (raw)

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

Don't populate the const array led_names on the stack but instead make
it static. Makes the object code smaller by 79 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  19686	   7952	    256	  27894	   6cf6	drivers/hid/hid-lg-g15.o

After:
   text	   data	    bss	    dec	    hex	filename
  19543	   8016	    256	  27815	   6ca7	drivers/hid/hid-lg-g15.o

(gcc version 10.2.0)
