Do we know why this is still dangerous for the user?
My plan is to make a sys/class driver to query write protection status
of the SPI, this will be
used by fwupd to gather information about vendors, also should be easy
for the user to use
'cat' and see the information from userspace. For this to be possible
we need kernel engineers
to compile the kernel with this driver enabled, but the (DANGEROUS)
tag is a no go for most
of them.
Is there anything I can do to make this possible?
Thanks
