Christophe JAILLET 7c799bc322 net: ieee802154: adf7242: Fix some potential buffer overflow in adf7242_stats_show() 
[ Upstream commit ca082f019d ]

strncat() usage in adf7242_debugfs_init() is wrong.
The size given to strncat() is the maximum number of bytes that can be
written, excluding the trailing NULL.

Here, the size that is passed, DNAME_INLINE_LEN, does not take into account
the size of "adf7242-" that is already in the array.

In order to fix it, use snprintf() instead.
