Subject: ieee802154: at86rf230: switch from BUG_ON() to WARN_ON() on problem
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=20f330452ad8814f2289a589baf65e21270879a7;p=linux.git

ieee802154: at86rf230: switch from BUG_ON() to WARN_ON() on problem

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