Subject: [PATCH] net: dsa: bcm_sf2: make const array static, makes object smaller
Date: Tue, 20 Oct 2020 17:50:29 +0100 [thread overview]
Message-ID: <20201020165029.56383-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the const array rate_table on the stack but instead it
static. Makes the object code smaller by 46 bytes.
Before:
text data bss dec hex filename
29812 3824 192 33828 8424 drivers/net/dsa/bcm_sf2.o
After:
text data bss dec hex filename
29670 3920 192 33782 83f6 drivers/net/dsa/bcm_sf2.o
(gcc version 10.2.0)
