fbdev: ssd1307fb: fix error return code
Propagate error code on failure. Also changed %ld to %d in dev_err to use
ret variable rather than putting two calls to PTR_ERR.
A simplified version of the semantic match that finds the first problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
identifier ret; expression e1,e2;
@@
(
if (\(ret < 0\|ret != 0\))
{ ... return ret; }
|
ret = 0
)
... when != ret = e1
when != &ret
*if(...)
{
... when != ret = e2
when forall
return ret;
}
// </smpl>
