Commit 7269cba53d90 ("tee: optee: Fix supplicant based device enumeration")
lead to the introduction of this bug. So fix it appropriately.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tee: optee: corrige el pánico del kernel causado por un manejo incorrecto de errores. La ruta de error al no poder registrar dispositivos en el bus TEE tiene un error que provoca el pánico del kernel de la siguiente manera: [15.398930] No se puede para manejar la solicitud de paginación del kernel en la dirección virtual ffff07ed00626d7c [15.406913] Información de cancelación de memoria: [15.409722] ESR = 0x0000000096000005 [15.413490] EC = 0x25: DABT (EL actual), IL = 32 bits [15.418814] SET = 0, FnV = 0 [ 15.421878] EA = 0, S1PTW = 0 [ 15.425031] FSC = 0x05: error de traducción de nivel 1 [ 15.429922] Información de cancelación de datos: [ 15.432813] ISV = 0, ISS = 0x00000005, ISS2 = 0x00000000 [ 15.438 310] CM = 0, WnR = 0, TnD = 0, TagAccess = 0 [15.443372] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 [15.448697] tabla de intercambio: páginas de 4k, VA de 48 bits, pgdp=00000000d9e3e000 [15.455413] 00626d7c] pgd=1800000bffdf9003, p4d=1800000bffdf9003, pud=0000000000000000 [15.464146] Error interno: Ups: 0000000096000005 [#1] PREEMPT SMP Commit 7269cba53d90 ("tee opt: ee: Reparar la enumeración de dispositivos basada en solicitantes") conducen a la introducción de este error. Así que arréglalo apropiadamente.
