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 <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
