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.
