Russ Meyerriecks 1813c9ad09 wcb4xxp: Prevent null pointer dereference on spanconfig In the rare case where spanconfig is called while there is pending data on the hdlc channel, the hdlc_getbuf interrupt could try to read from the hdlc buffer before the channel was fully setup. This could potentially result in a null pointer dereference. This condition has existed since the creation of the wcb4xxp driver.

Russ Meyerriecks 1813c9ad09 wcb4xxp: Prevent null pointer dereference on spanconfig

In the rare case where spanconfig is called while there is pending data
on the hdlc channel, the hdlc_getbuf interrupt could try to read from
the hdlc buffer before the channel was fully setup. This could
potentially result in a null pointer dereference. This condition has
existed since the creation of the wcb4xxp driver.
