bluetooth: rfcomm_init bug fix
rfcomm tty may be used before rfcomm_tty_driver initilized, The problem is that now socket layer init before tty layer, if userspace program do socket callback right here then oops will happen. reporting in: http://marc.info/?l=linux-bluetooth&m=124404919324542&w=2 make 3 changes: 1. remove #ifdef in rfcomm/core.c, make it blank function when rfcomm tty not selected in rfcomm.h 2. tune the rfcomm_init error patch to ensure tty driver initilized before rfcomm socket usage. 3. remove __exit for rfcomm_cleanup_sockets because above change need call it in a __init function.
