[PATCH 4/4] md: Fix the return value of mddev_stack_new_rdev

[linan666]

From: Li Nan <linan122@xxxxxxxxxx>

In mddev_stack_new_rdev(), if the integrity profile check fails, it
returns -ENXIO, which means "No such device or address". This is
inaccurate and can mislead users. Change it to return -EINVAL.

Fixes: c6e56cf6b2e7 ("block: move integrity information into queue_limits")
