Subject: [PATCH] HID: prodikeys: make array keys static const, makes object smaller
Date: Thu, 5 Sep 2019 17:54:06 +0100 [thread overview]
Message-ID: <20190905165406.24641-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the array keys on the stack but instead make it
static const. Makes the object code smaller by 166 bytes.
Before:
text data bss dec hex filename
18931 5872 480 25283 62c3 drivers/hid/hid-prodikeys.o
After:
text data bss dec hex filename
18669 5968 480 25117 621d drivers/hid/hid-prodikeys.o
(gcc version 9.2.1, amd64)
