nfc: st-nci: fix incorrect validating logic in EVT_TRANSACTION
stable inclusion from stable-v5.10.157 commit e14583073fc0f31b35b7de4eefbb1e2720914e0f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7MU59 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e14583073fc0f31b35b7de4eefbb1e2720914e0f -------------------------------- [ Upstream commit c60c1522 ] The first validation check for EVT_TRANSACTION has two different checks tied together with logical AND. One is a check for minimum packet length, and the other is for a valid aid_tag. If either condition is true (fails), then an error should be triggered. The fix is to change && to ||.
