Christophe JAILLET 20b9527ebe ACPI: sysfs: Fix create_pnp_modalias() and create_of_modalias() 
[ Upstream commit 48cf49d319 ]

snprintf() does not return negative values on error.

To know if the buffer was too small, the returned value needs to be
compared with the length of the passed buffer. If it is greater or
equal, the output has been truncated, so add checks for the truncation
to create_pnp_modalias() and create_of_modalias(). Also make them
return -ENOMEM in that case, as they already do that elsewhere.

Moreover, the remaining size of the buffer used by snprintf() needs to
be updated after the first write to avoid out-of-bounds access as
already done correctly in create_pnp_modalias(), but not in
create_of_modalias(), so change the latter accordingly.

Fixes: 8765c5ba19 ("ACPI / scan: Rework modalias creation when "compatible" is present")
