The following patch adds error checking to the copy_*_user() functions
to the remaining WAN drivers which did not have this checking made. I'm
sending a single patch as it's the same change in all files. Affected
files are:

drivers/net/wan/comx-hw-comx.c
drivers/net/wan/comx-hw-locomx.c
drivers/net/wan/comx-hw-mixcom.c
drivers/net/wan/comx-hw-munich.c
drivers/net/wan/comx-proto-fr.c
drivers/net/wan/comx-proto-lapb.c
drivers/net/wan/pc300_drv.c
drivers/net/wan/sbni.c

Applies cleanly on top of latest bk(-19). Please consider applying.
