Data allocated with devm_ioremap or devm_ioremap_nocache should not be
freed using iounmap, because doing so causes a dangling pointer, and a
subsequent double free.
The semantic match that finds this problem is as follows:
x = devm_ioremap(...)
x = devm_ioremap_nocache(...)
surely this semantic patch script is worth adding to scripts/coccinelle?
Are you going to take care of this?
