Subject: [PATCH 01/11 v2] MIPS: Alchemy: constify gpio_led

gpio_led are not supposed to change at runtime.
struct gpio_led_platform_data working with const gpio_led
provided by <linux/leds.h>. So mark the non-const structs
as const.

Signed-off-by: Arvind Yadav <[email protected]>

changes in v2:
The GPIO LED driver can be built as a module, it can
be loaded after the init sections have gone away.
So removed '__initconst'.

changes in v2:
The GPIO LED driver can be built as a module, it can
be loaded after the init sections have gone away.
So removed '__initconst'.

Subject: [PATCH 11/11 v2] ARM: pxa: constify gpio_led

gpio_led are not supposed to change at runtime.
struct gpio_led_platform_data working with const gpio_led
provided by <linux/leds.h>. So mark the non-const structs
as const.

The GPIO LED driver can be built as a module, it can
