Subject: [PATCH] mmc: sunxi: remove output of virtual base address
Date: Tue, 17 Jul 2018 11:09:58 +0100 [thread overview]
Message-ID: <20180717100958.12042-1-andre.przywara@arm.com> (raw)
Recent Linux versions refuse to print actual virtual kernel addresses,
to not give a hint about the location of the kernel in a randomized virtual
address space. This affects the output of the sunxi MMC controller
driver, which now produces the rather uninformative line:
[ 1.482660] sunxi-mmc 1c0f000.mmc: base:0x(____ptrval____) irq:8
Since the virtual base address is not really interesting in the first
place, let's just drop this value. We have the physical address as part
of the DT node name, which is way more useful for debugging purposes.
