Hi Tony, all, During the kernel boot I see the following error. The device is still working afterwards. 5.17.5 shows the same behavior. Is this a known issue? [ 3.734570] sdhci-omap 48060000.mmc: Got CD GPIO [ 3.739989] INFO: trying to register non-static key. [ 3.744991] The code is fine but needs lockdep annotation, or maybe [ 3.751286] you didn't initialize this object before use? [ 3.756707] turning off the locking correctness validator.
