Right, this one needs an __iomem annotation on the 'pcfg' pointer.

Same here, the driver is completely lacking any __iomem annotations.
It has only seen cosmetic updates since it was introduced in 2012.

I wonder why Kernel Test Robot notifies about this code for this branch.
This is a branch with only ioread-const unification. Although commits
touched included header linux/io-64-nonatomic-lo-hi.h but only constness
was affected. Therefore all these warnings should exist before as well.
Best regards,

I just double checked - the warnings were there already, before my patches.

I think the email gets sent because the warning text changed from before, now
it expects a 'const __iomem void*' argument rather than an '__iomem void *',
and the script is not smart enough to tell that this is the same bug as before.
