Subject: [PATCH 1/2] libweston/backend-fbdev/fbdev.c: don't destroy output
twice
This is currently unsupported and may result in a segfault.
fbdev_output_disable(base) does call pixman_renderer_output_destroy(base) so
one should not do it a second time here.
Observed on a colibri-imx6ull which actually uses pixman for rendering.
Program received signal SIGSEGV, Segmentation fault.
