From: Christophe JAILLET Date: Tue, 12 Nov 2024 21:12:25 +0000 (+0100) Subject: drm/bridge: Constify struct i2c_device_id X-Git-Tag: v6.14-rc1~174^2~18^2~91 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=dbf7986f8a56ce47465bb6e0f2b2d166b931d707;p=thirdparty%2Fkernel%2Flinux.git drm/bridge: Constify struct i2c_device_id 'struct i2c_device_id' is not modified in these drivers. Constifying this structure moves some data to a read-only section, so increase overall security. On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 15566 987 32 16585 40c9 drivers/gpu/drm/bridge/chipone-icn6211.o After: ===== text data bss dec hex filename 15630 923 32 16585 40c9 drivers/gpu/drm/bridge/chipone-icn6211.o Signed-off-by: Christophe JAILLET Acked-by: Douglas Anderson Reviewed-by: Laurent Pinchart Signed-off-by: Douglas Anderson Link: https://patchwork.freedesktop.org/patch/msgid/bdba1f49b4b48e22628482b49ce81f8e1f0d97b1.1731445901.git.christophe.jaillet@wanadoo.fr --- diff --git a/drivers/gpu/drm/bridge/chipone-icn6211.c b/drivers/gpu/drm/bridge/chipone-icn6211.c index 9eecac457dcf5..d47703559b0de 100644 --- a/drivers/gpu/drm/bridge/chipone-icn6211.c +++ b/drivers/gpu/drm/bridge/chipone-icn6211.c @@ -785,7 +785,7 @@ static struct mipi_dsi_driver chipone_dsi_driver = { }, }; -static struct i2c_device_id chipone_i2c_id[] = { +static const struct i2c_device_id chipone_i2c_id[] = { { "chipone,icn6211" }, {}, }; diff --git a/drivers/gpu/drm/bridge/lontium-lt9211.c b/drivers/gpu/drm/bridge/lontium-lt9211.c index c8881796fba4c..999ddebb832de 100644 --- a/drivers/gpu/drm/bridge/lontium-lt9211.c +++ b/drivers/gpu/drm/bridge/lontium-lt9211.c @@ -773,7 +773,7 @@ static void lt9211_remove(struct i2c_client *client) drm_bridge_remove(&ctx->bridge); } -static struct i2c_device_id lt9211_id[] = { +static const struct i2c_device_id lt9211_id[] = { { "lontium,lt9211" }, {}, }; diff --git a/drivers/gpu/drm/bridge/lontium-lt9611.c b/drivers/gpu/drm/bridge/lontium-lt9611.c index 1b31fdebe1640..8f25b338a8d8f 100644 --- a/drivers/gpu/drm/bridge/lontium-lt9611.c +++ b/drivers/gpu/drm/bridge/lontium-lt9611.c @@ -1235,7 +1235,7 @@ static void lt9611_remove(struct i2c_client *client) of_node_put(lt9611->dsi0_node); } -static struct i2c_device_id lt9611_id[] = { +static const struct i2c_device_id lt9611_id[] = { { "lontium,lt9611", 0 }, {} }; diff --git a/drivers/gpu/drm/bridge/lontium-lt9611uxc.c b/drivers/gpu/drm/bridge/lontium-lt9611uxc.c index 4d1d40e1f1b4d..f89af8203c9d6 100644 --- a/drivers/gpu/drm/bridge/lontium-lt9611uxc.c +++ b/drivers/gpu/drm/bridge/lontium-lt9611uxc.c @@ -913,7 +913,7 @@ static void lt9611uxc_remove(struct i2c_client *client) of_node_put(lt9611uxc->dsi0_node); } -static struct i2c_device_id lt9611uxc_id[] = { +static const struct i2c_device_id lt9611uxc_id[] = { { "lontium,lt9611uxc", 0 }, { /* sentinel */ } }; diff --git a/drivers/gpu/drm/bridge/ti-sn65dsi83.c b/drivers/gpu/drm/bridge/ti-sn65dsi83.c index 57a7ed13f9965..00d3bfa645f5a 100644 --- a/drivers/gpu/drm/bridge/ti-sn65dsi83.c +++ b/drivers/gpu/drm/bridge/ti-sn65dsi83.c @@ -732,7 +732,7 @@ static void sn65dsi83_remove(struct i2c_client *client) drm_bridge_remove(&ctx->bridge); } -static struct i2c_device_id sn65dsi83_id[] = { +static const struct i2c_device_id sn65dsi83_id[] = { { "ti,sn65dsi83", MODEL_SN65DSI83 }, { "ti,sn65dsi84", MODEL_SN65DSI84 }, {}, diff --git a/drivers/gpu/drm/bridge/ti-sn65dsi86.c b/drivers/gpu/drm/bridge/ti-sn65dsi86.c index 9e31f750fd889..ce4c026b064f7 100644 --- a/drivers/gpu/drm/bridge/ti-sn65dsi86.c +++ b/drivers/gpu/drm/bridge/ti-sn65dsi86.c @@ -1970,7 +1970,7 @@ static int ti_sn65dsi86_probe(struct i2c_client *client) return ti_sn65dsi86_add_aux_device(pdata, &pdata->aux_aux, "aux"); } -static struct i2c_device_id ti_sn65dsi86_id[] = { +static const struct i2c_device_id ti_sn65dsi86_id[] = { { "ti,sn65dsi86", 0}, {}, };
