X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e4129a9ccea54e8f4fbc408476120059809a4627;p=openwrt%2Fstaging%2Fblogic.git V4L/DVB (11277): tvaudio: always call init_timer to prevent rmmod crash. In the tvaudio_remove function del_timer_sync(&chip->wt) is called. However, chip->wt isn't always initialized depending on the type of audio chip. Since del_timer_sync hangs when given an uninitialized timer we should always initialize it.
