[PATCH 4.9 090/130] ieee802154: fakelb: switch from BUG_ON() to WARN_ON() on problem

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

[ Upstream commit 8f2fbc6c60ff213369e06a73610fc882a42fdf20 ]

The check is valid but it does not warrant to crash the kernel. A
WARN_ON() is good enough here.
