staging: unisys: visorinput: convert pr_err() to dev_err()

Replace pr_err() calls with respective dev_err() counterpart.
Semantic patch used to detect and apply the transformation:

@r exists@
identifier f,s,i;
position p;
@@

f(...,struct s *i,...) {
  <+...
  pr_err@p(...)
  ...+>
}

@s@
identifier r.s, dev;
@@

struct s {
	...
	struct device dev;
	...
};

@t@
identifier r.i, s.dev;
expression fmt;
position r.p;
@@

- pr_err@p(
+ dev_err(&i->dev,
			fmt, ...);
