The memconsole driver is not using proper accessors for __iomem. Switch
to memremap to fix this issue, and this also prepares the driver for the
removal of ioremap_cache.

Could you maintain the existing style of the broken line alignment in this
file?
if (!memconsole) {
- pr_err("memconsole: ioremap_cache failed\n");
+ pr_err("memconsole: memremap failed\n");
return -ENOMEM;
}
ret = memory_read_from_buffer(buf, count, &pos, memconsole,
memconsole_length);
Here's an example...
- iounmap(memconsole);
+ memunmap(memconsole);
return ret;
}
