From 4ce8e88f6c25469b83a7d56914995fe892d1f9a8 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 21 Sep 2017 23:30:07 +0100 Subject: i2c: designware: make const array supported_speeds static to shink object code size Don't populate const array supported_speeds on the stack, instead make it static. Makes the object code smaller by 150 bytes: Before: text data bss dec hex filename 8474 1440 0 9914 26ba i2c-designware-platdrv.o After: text data bss dec hex filename 8324 1440 0 9764 2624 i2c-designware-platdrv.o (gcc version 7.2.0 x86_64) Signed-off-by: Colin Ian King Acked-by: Jarkko Nikula Signed-off-by: Wolfram Sang --- drivers/i2c/busses/i2c-designware-platdrv.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'drivers/i2c') diff --git a/drivers/i2c/busses/i2c-designware-platdrv.c b/drivers/i2c/busses/i2c-designware-platdrv.c index 16c027b62a20..58add69a441c 100644 --- a/drivers/i2c/busses/i2c-designware-platdrv.c +++ b/drivers/i2c/busses/i2c-designware-platdrv.c @@ -265,7 +265,9 @@ static int dw_i2c_plat_probe(struct platform_device *pdev) u32 acpi_speed, ht = 0; struct resource *mem; int i, irq, ret; - const int supported_speeds[] = { 0, 100000, 400000, 1000000, 3400000 }; + static const int supported_speeds[] = { + 0, 100000, 400000, 1000000, 3400000 + }; irq = platform_get_irq(pdev, 0); if (irq < 0) -- cgit
