What is the standard of review of a search warrant application?

"On appeal from the denial of a motion to suppress [citation], our standard of review is settled. We defer to the trial court's express or implied factual findings if supported by substantial evidence, but independently apply constitutional principles to the trial court's factual findings in determining the legality of the search. [Citations.] Appellate review `is confined to the correctness or incorrectness of the trial court's ruling, not the reasons for its ruling.'" (People v. Baker (2008) 164 Cal.App.4th 1152, 1156.)
