Hi Hans and Mauro,

While I was making changes for media token work, I noticed there are
several places au0828_init_tuner() gets called without holding dev lock.

vidioc_s_std(), vidioc_g_tuner(), vidioc_s_tuner(), vidioc_streamon()
au0828_v4l2_resume()

Some of these might be intended since au0828_init_tuner() invokes
s_std. All of these changes including the au0828_init_tuner() itself
were added in ea86968fb91471493ccac7d8f2a65bc65db6803b

au0828_v4l2_resume() also does this and this one for sure needs fixing
very likely. I am not sure about the others. Thoughts??
