	these drivers use tasklets or irq apis, but don't include interrupt.h. Once flow cache is removed the implicit interrupt.h inclusion goes away which will break the build. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-06-16	networking: introduce and use skb_put_data()	Johannes Berg
	A common pattern with skb_put() is to just want to memcpy() some data into the new space, introduce skb_put_data() for this. An spatch similar to the one for skb_put_zero() converts many of the places using it: @@ identifier p, p2; expression len, skb, data; type t, t2; @@ ( -p = skb_put(skb, len); +p = skb_put_data(skb, data, len); \| -p = (t)skb_put(skb, len); +p = skb_put_data(skb, data, len); ) ( p2 = (t2)p; -memcpy(p2, data, len); \| -memcpy(p, data, len); ) @@ type t, t2; identifier p, p2; expression skb, data; @@ t p; ... ( -p = skb_put(skb, sizeof(t)); +p = skb_put_data(skb, data, sizeof(t)); \| -p = (t )skb_put(skb, sizeof(t)); +p = skb_put_data(skb, data, sizeof(t)); ) ( p2 = (t2)p; -memcpy(p2, data, sizeof(p)); \| -memcpy(p, data, sizeof(p)); ) @@ expression skb, len, data; @@ -memcpy(skb_put(skb, len), data, len); +skb_put_data(skb, data, len); (again, manually post-processed to retain some comments) Reviewed-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S.

2017-05-23	net: ieee802154: fix potential null pointer dereference	Gustavo A. R. Silva
	Null check at line 918: if (!spi) {, implies spi might be NULL. Function spi_get_drvdata() dereference pointer spi. Move pointer priv assignment after the null check.

2017-04-12	ieee802154: ca8210: Add checks for kmalloc allocation failures	Colin Ian King
	Ensure we don't end up with a null pointer dereferences by checking for for allocation failures. Allocate by sizeof(*ptr) rather than the type to fix checkpack warnings. Also merge multiple lines into one line for the kmalloc call.

2017-04-12	ieee802154: Add CA8210 IEEE 802.15.4 device driver	Harry Morris
	Add driver source and config for softMAC implementation of Cascoda's CA8210 IEEE 802.15.4 transceiver device. The driver mimics a common PHY-only implementation despite the CA8210 being a hardMAC device which exposes a SAP interface to the fully integrated MAC. The chip is a modem-only device with an integrated processor which runs the 802.15.4 MAC. The chip communicates via full-duplex SPI with additional pins for NIRQ and NRESET. The chip can also output its 16MHz clock to a GPIO with a configurable divider. The driver can be configured to implement a debugfs node that provides access to the SAP-based API to drive mechanisms not currently supported by the standard kernel interface.
