Christian Marangi 796d3fad8c PM / devfreq: Fix buffer overflow in trans_stat_show ... [ Upstream commit 08e23d05fa6dc4fc13da0ccf09defdd4bbc92ff4 ] Fix buffer overflow in trans_stat_show(). Convert simple snprintf to the more secure scnprintf with size of PAGE_SIZE. Add condition checking if we are exceeding PAGE_SIZE and exit early from loop. Also add at the end a warning that we exceeded PAGE_SIZE and that stats is disabled. Return -EFBIG in the case where we don't have enough space to write the full transition table. Also document in the ABI that this function can return -EFBIG error.
