Christophe JAILLET f6a14247f9 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.
