Subject: [PATCH] drm/pl111: Fix regression from fbdev CMA helper
Date: Mon, 12 Feb 2018 13:40:19 +0100	[thread overview]
Message-ID: <20180212124019.25268-1-linus.walleij@linaro.org> (raw)

Commit d18df744de1a ("drm/pl111: Use drm_fb_cma_fbdev_init/fini()")
refactored the driver to use fbdev handling in the core, but
mistakedly limited the number of maximum connections to 0.

Predictably, zero possible connections also gives zero
framebuffers when using the system. So let's bump it to 1 so
we get our framebuffer back.
