+Subject: [PATCH] io_url_wget: correctly init wget_out on apk_io_url_init call
+
+Commit fc7768c09497 ("io_url_wget: log wget output using apk_process
+api") reworked the implementation but forgot to init the static wget_out
+on calling apk_io_url_init. This cause APK to SIGFAULT on apk update or
+apk add when actually using the WGET method to download remote packages.
+
+Fix this by setting wget_out with the passed out from apk_io_url_init.
