This patch replaces pr_debug calls with dev_dbg when the device structure
is available as dev_* prints identifying information about the struct
device.
Done using coccinelle:
@r exists@
identifier f, s;
identifier x;
position p;
@@
f(...,struct s *x,...) {
<+...
when != x == NULL
\(pr_err@p\|pr_debug@p\|pr_info\)(...);
...+>
}
