You may have "compile tested", but you certainly didn't watch out
for new warnings:
drivers/net/wan/cycx_drv.c: In function 'cycx_setup':
drivers/net/wan/cycx_drv.c:141:2: warning: passing argument 1 of 'get_option_index' discards qualifiers from pointer target type
drivers/net/wan/cycx_drv.c:76:12: note: expected 'long int *' but argument is of type 'const long int *'
drivers/net/wan/cycx_drv.c:151:2: warning: passing argument 1 of 'get_option_index' discards qualifiers from pointer target type
drivers/net/wan/cycx_drv.c:76:12: note: expected 'long int *' but argument is of type 'const long int *'
I've reverted your patch.
