From: Linus Walleij Date: Thu, 10 Mar 2016 08:48:06 +0000 (+0700) Subject: gpio: uapi: use 0xB4 as ioctl() major X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fae98164463948eb31d638fe207c25a3d2b9312f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git gpio: uapi: use 0xB4 as ioctl() major The previous 'o' is in conflict and not very orderly assigned. We want to select an ioctl() major that does not conflict with the existining ones. Add the new reserved major (0xB4) to Documentation/ioctl/ioctl-number.txt Fixes: 3c702e9987e2 ("gpio: add a userspace chardev ABI for GPIOs") Suggested-by: Arnd Bergmann Signed-off-by: Linus Walleij --- diff --git a/Documentation/ioctl/ioctl-number.txt b/Documentation/ioctl/ioctl-number.txt index 91261a32a573..9369d3b0f09a 100644 --- a/Documentation/ioctl/ioctl-number.txt +++ b/Documentation/ioctl/ioctl-number.txt @@ -319,6 +319,7 @@ Code Seq#(hex) Include File Comments 0xB1 00-1F PPPoX 0xB3 00 linux/mmc/ioctl.h +0xB4 00-0F linux/gpio.h 0xC0 00-0F linux/usb/iowarrior.h 0xCA 00-0F uapi/misc/cxl.h 0xCA 80-8F uapi/scsi/cxlflash_ioctl.h diff --git a/include/uapi/linux/gpio.h b/include/uapi/linux/gpio.h index dfe8ade2742d..d0a3cac72250 100644 --- a/include/uapi/linux/gpio.h +++ b/include/uapi/linux/gpio.h @@ -52,7 +52,7 @@ struct gpioline_info { char consumer[32]; }; -#define GPIO_GET_CHIPINFO_IOCTL _IOR('o', 0x01, struct gpiochip_info) -#define GPIO_GET_LINEINFO_IOCTL _IOWR('o', 0x02, struct gpioline_info) +#define GPIO_GET_CHIPINFO_IOCTL _IOR(0xB4, 0x01, struct gpiochip_info) +#define GPIO_GET_LINEINFO_IOCTL _IOWR(0xB4, 0x02, struct gpioline_info) #endif /* _UAPI_GPIO_H_ */
