Check os_snprintf() result more consistently - automatic 1
This converts os_snprintf() result validation cases to use os_snprintf_error() where the exact rule used in os_snprintf_error() was used. These changes were done automatically with spatch using the following semantic patch: @@ identifier E1; expression E2,E3,E4,E5,E6; statement S1; @@ ( E1 = os_snprintf(E2, E3, ...); | int E1 = os_snprintf(E2, E3, ...); | if (E5) E1 = os_snprintf(E2, E3, ...); else E1 = os_snprintf(E2, E3, ...); | if (E5) E1 = os_snprintf(E2, E3, ...); else if (E6) E1 = os_snprintf(E2, E3, ...); else E1 = 0; | if (E5) { ...
