    [media] BKL: trivial BKL removal from V4L2 radio drivers · 32958fdd
    Hans Verkuil authored
    The patch converts a bunch of V4L2 radio drivers to unlocked_ioctl.
    
    These are all simple conversions: most already had a lock and so the ioctl
    fop could simply be replaced by unlocked_ioctl.
    
    radio-miropcm20.c was converted to use the new V4L2 core lock.
    
    While doing this work I noticed that many of these drivers initialized
    some more fields or muted audio or something like that *after* creating
    the device node. This should be done before the device node is created
    to prevent problems. Especially hal tends to grab a device node as soon
    as it is created.
    
    In one or two cases the mutex_init was even done after the device creation!
