Is an affidavit supporting probable cause supported by probable cause insufficient?

^3. " 'In determining whether an affidavit is supported by probable cause, the magistrate must make a "practical, common-sense decision whether, given all the circumstances set forth in the affidavit . . . there is a fair probability that contraband or evidence of a crime will be found in a particular place." ' " (People v. Garcia (2003) 111 Cal.App.4th 715, 720.) "[A]n affidavit based on mere suspicion or belief, or stating a conclusion with no supporting facts, is wholly insufficient." (Id. at p. 721.)
