Laurent Pinchart a517cca6b2 [media] media: vb2: Fix potential deadlock in vb2_prepare_buffer ... Commit b037c0fde2 ("media: vb2: fix potential deadlock in mmap vs. get_userptr handling") fixes an AB-BA deadlock related to the mmap_sem and driver locks. The same deadlock can occur in vb2_prepare_buffer(), fix it the same way.
