stable inclusion from stable-v6.6.33 commit 755575a42c4f77bf135feed21cc40b45d902b001 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 24034af644fc01126bec9850346a06ef1450181f ]
Since commit 63b0cd30b78e ("media: ov2680: Add bus-cfg / endpoint property verification") the ov2680 driver no longer probes when the 'data-lanes' property is absent.
The OV2680 sensor has only one data lane, so there is no need for describing it the devicetree.
Remove the unnecessary data-lanes property check.
