| H A D | sil-sii8620.c | diff 02cd2d3144653e6e2a0c7ccaa73311e48e2dc686 Sun Jul 12 10:24:53 CDT 2020 Tom Rix <trix@redhat.com> drm/bridge: sil_sii8620: initialize return of sii8620_readb
clang static analysis flags this error
sil-sii8620.c:184:2: warning: Undefined or garbage value
returned to caller [core.uninitialized.UndefReturn]
return ret;
^~~~~~~~~~
sii8620_readb calls sii8620_read_buf.
sii8620_read_buf can return without setting its output
pararmeter 'ret'.
So initialize ret.
