Check os_snprintf() result more consistently - success case
This converts os_snprintf() result validation cases to use os_snprintf_error() in cases where success condition was used to execute a step. These changes were done automatically with spatch using the following semantic patch: @@ expression E1,E2,E3; statement S1; @@ E1 = os_snprintf(E2, E3, ...); - if (\( E1 >= 0 \| E1 > 0 \) && \( (size_t) E1 < E3 \| E1 < (int) E3 \| E1 < E3 \)) + if (!os_snprintf_error(E3, E1)) S1 Signed-off-by: Jouni Malinen <j@w1.fi>
