Hi Dave,
drivers/gpu/vga/vga_switcheroo.c +362 vga_switcheroo_debugfs_write(101)
277 mutex_lock(&vgasr_mutex);
278
279 if (!vgasr_priv.active)
280 return -EINVAL;
Is there a reason we return with the lock held here? The other returns
from this function don't have the lock held. I looked through the rest
of the file but didn't see any clues.
regards,
dan carpenter
