In case of error, the function ioremap() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

Have you made this into a scripts/coccinelle/ script I can run?
Applied to clk-next

I added the fix Wei Yongjun indicated ( Thanks Wei !)
and another fix similar to the above + error print change.
I'm a newbie... what's scripts/coccinelle/ script ?
I just made a new patch same way I did before. Is this OK?

With Coccinelle, you can make a rule that can be put into the Linux kernel
that can allow others to find this problem automatically. Maybe:
@@
expression e,e1;
statement S1,S2;
@@
e = ioremap(...);
... when != e = e1
if (
- IS_ERR(e)
+ !e
)
S1 else S2
