[PATCH v2 2/2] Input: uinput: return -EINVAL for out-of-range UI_ABS_SETUP axis code

[Iván Ezequiel Rodriguez]

uinput_abs_setup() rejects an axis code above ABS_MAX with -ERANGE, but
the UI_ABS_SETUP documentation in include/uapi/linux/uinput.h states the
ioctl may only fail with -EINVAL, -ENOMEM or -EFAULT. An out-of-range
code is exactly the "incorrect values" case described there, and every
other validation failure in this path already returns -EINVAL.

Return -EINVAL so the code matches its documented uapi contract.
