Tom Rix a135b366c3 drm/bridge: sil_sii8620: initialize return of sii8620_readb 
[ Upstream commit 02cd2d3144 ]

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.
