drm/framebuffer: Fix use of uninitialized variable
[ Upstream commit f9af8f0c1dc567a5a6a6318ff324c45d80d4a60f ]
smatch reports:
drivers/gpu/drm/drm_framebuffer.c:654 drm_mode_getfb2_ioctl() error: uninitialized symbol 'ret'.
'ret' is possibly not set when there are no errors, causing the error
above. I can't say if that ever happens in real-life, but in any case I
think it is good to initialize 'ret' to 0.
