media: ivsc: csi: add separate lock for v4l2 control handler
There're possibilities that privacy status change notification happens
in the middle of the ongoing mei command which already takes the command
lock, but v4l2_ctrl_s_ctrl() would also need the same lock prior to this
patch, so this may results in circular locking problem. This patch adds
one dedicated lock for v4l2 control handler to avoid described issue.
Fixes: 29006e196a56 ("media: pci: intel: ivsc: Add CSI submodule")
Cc: [email protected] # for 6.6 and later
